Wikipedia
Wikipedia (
IPA: , or , else ) is an
international Web-based
free-content encyclopedia project. It exists as a
wiki, a
website that allows visitors to edit its content. The word
Wikipedia itself is a
portmanteau of the words
wiki and
encyclopedia. Wikipedia is written collaboratively by
volunteers, allowing most articles to be changed by anyone with access to the website. Wikipedia's main servers are in
Tampa, Florida, with additional servers in
Amsterdam and
Seoul.
The project began in January 2001, as a complement to the expert-written (and now defunct)
Nupedia, and is now operated by the
non-profit Wikimedia Foundation. It was created by
Larry Sanger and
Jimmy Wales; however, Sanger resigned from both Nupedia and Wikipedia on
March 1,
2002.
As of August 2006, Wikipedia has more than 4,600,000 articles in many languages, including more than 1,300,000 in the
English-language version. There are more than 200 language editions of Wikipedia, fifteen of which have more than 50,000 articles each. The
German-language edition has been distributed on , and there have also been proposals for an English DVD or print edition. Since its inception, Wikipedia has steadily risen in popularity,
[See plots at "Visits per day", Wikipedia Statistics, January 1, 2005] and has spawned several sister projects. According to
Alexa (an internet traffic observer), Wikipedia is ranked among the top 20 most visited websites, and many of its pages have been
mirrored or
forked by other sites, such as
Answers.com.
Wikipedia's co-founder,
Jimmy Wales, has called Wikipedia "an effort to create and distribute a
multilingual free encyclopedia of the highest possible quality to every single person on the planet in their own language."
[Jimmy Wales, "Wikipedia is an encyclopedia", March 8, 2005, ] However, there has been controversy over Wikipedia's reliability and accuracy, with the site receiving criticism for its susceptibility to vandalism, uneven quality and inconsistency,
systemic bias, and preference for
consensus or popularity over
credentials. Despite this, its free distribution, constant and plentiful updates, diverse coverage, lack of advertising, and versions in numerous languages have made it a popular Internet destination.
Wikipedia's official slogan is "the free encyclopedia that anyone can edit"; developed using a type of
software called a "
wiki", a term originally used for the
WikiWikiWeb and derived from the
Hawaiian wiki wiki, which means "quick". One of the encyclopedia's main advantages is its ability to update quickly as events unfold and valuable new information becomes available.
Although other
encyclopedia projects exist or have existed on the Internet, few achieved Wikipedia's size or popularity. Traditional multilingual editorial policies and article ownership are used in particular, such as the expert-written
Stanford Encyclopedia of Philosophy, the now-defunct
Nupedia, and the more casual
h2g2 and
Everything2. Projects such as Wikipedia,
Susning.nu,
Enciclopedia Libre and
WikiZnanie are other wikis in which articles are developed by numerous authors, and there is no formal process of review. Unlike many encyclopedias, it has licensed its content under the
GNU Free Documentation License (GFDL).
Wikipedia has a set of policies identifying types of information appropriate for inclusion. These policies are often cited in disputes over whether particular content should be added, revised, transferred to a sister project, or removed. One of Wikipedia's core policies is that articles must be written from a "neutral point of view", presenting all noteworthy perspectives on an issue along with the evidence supporting them. The project also forbids the use of
original research. Wikipedia articles do not attempt to determine an
objective truth on their subjects, but rather to describe them impartially balancing all significant viewpoints. Following the introduction of a more
user friendly citation functionality (
cite.php, early 2006), articles increasingly include an extensive reference sections to support the information presented in the article.
Free content
The
GFDL, the license through which Wikipedia's articles are made available, is one of many "
copyleft" licenses that permit the redistribution, creation of
derivative works, and commercial use of content, provided that its authors are attributed and this content remains available under the GFDL. When an author contributes original material to the project, the
copyright over it is retained by them, but they agree to make the work available under the GFDL.
Wikipedia's content has been reflected and forked by hundreds of resources from database dumps. Although all text is available under the GFDL, a significant percentage of Wikipedia's images and sounds are not free. Items such as
corporate logos, song samples, or copyrighted news photos are used with a claim of
fair use.
["Wikipedia as a press source (2005)", Wikipedia (March 28, 2005)] Wikipedia content has also been used in academic studies, books and conferences, albeit more rarely, and very recently, in movies. Wikipedia was once used in a United States court case,
[Bourgeois et al v. Peters et al.] and the
Parliament of Canada website refers to Wikipedia's article on
same-sex marriage in the "further reading" list of
Civil Marriage Act.
["C-38", LEGISINFO (March 28, 2005)] Some Wikipedia users, or
Wikipedians, maintain (noncomprehensive) lists of such uses.

An example of Wikipedia's range in language editions: Wikipedia in Hebrew.[http://he.wikipedia.org/wiki/] |
Language editions
Wikipedia encompasses 151 "active" language editions (ones with 100+ articles) as of July 2006.
["List of Wikipedias", Meta-Wiki, April 15, 2006] In total, Wikipedia contains 229 language editions of varying states, with a combined 4 million articles.
["Complete list of language Wikipedias available", Meta-Wiki, April 15, 2006]Language editions operate independently from one another. Editions are not bound to the content of other language editions, nor are articles on the same subject required to be translations of each other. Automated translation of articles is explicitly disallowed, though multilingual editors of sufficient fluency are encouraged to manually translate articles. The various language editions
are held to global policies such as "neutral point of view", though they may diverge on subtler points of policy and practice. Articles and images are shared between Wikipedia editions, the former through "
InterWiki" links and pages to request translations, and the latter through the
Wikimedia Commons repository. Translated articles represent only a small portion of articles in most editions.
[For example, "Translation into English," Wikipedia. (March 9, 2005)] |
Wikipedia's article count has shown rapid growth in some of the major language editions. |
The following is a list of the largest editions—the ones with 100,000+ articles—sorted by number of articles as of
July 19,
2006. (Note that the article count, however, is a limited metric for comparing the editions, for a variety of reasons. In some Wikipedia versions, for example, nearly half of the articles are short articles created automatically by
robots.
Further, many editions that have more articles also have fewer contributors. Although the Polish, Dutch, Portuguese, Swedish and Italian Wikipedias have more articles than the Spanish Wikipedia, they have fewer users.)
According to
Alexa Internet's audience measurement service, the English sub-domain (en.wikipedia.org) gets just over 60% of Wikipedia's cumulative traffic, with the remaining 40% being splintered between the numerous other languages in which Wikipedia is offered.

Editing
|
Editors keep track of changes to articles by checking the difference between two revisions of a page, displayed here in red. |
Almost all visitors may edit Wikipedia's content, and registered users can create new articles and have their changes instantly displayed. Wikipedia is built on the expectation that collaboration among users will improve articles over time, in much the same way that
open-source software develops. Some of Wikipedia's editors have explained its editing process as a "
socially Darwinian evolutionary process".
["Wikipedia sociology", Meta-Wiki, 23:30 March 24]Although many viewers take advantage of Wikipedia's openness to add nonsense to the encyclopedia, most deliberately disruptive edits and comments are quickly found and deleted by other editors. This real-time, collaborative model allows editors to rapidly update existing topics as they develop and to introduce new ones as they arise. However, this collaboration also sometimes leads to "edit wars" and prolonged disputes when editors do not agree.
["Edit war", Wikipedia (March 26, 2005)] |
The "recent changes" page shows the newest edits to the English Wikipedia. This page is often watched by users who revert vandalism. There is also a live recent changes IRC channel, [irc://irc.wikimedia.org/en.wikipedia #en.wikipedia @ irc.wikimedia.org]. |
Articles are always subject to editing, unless the article is protected for a short time due to the aforementioned vandalism or revert wars; Wikipedia does not declare any of its articles to be "complete" or "finished". The authors of articles need not have any expertise or formal qualifications in the subjects that they edit, and users are warned that their contributions may be "edited mercilessly and redistributed at will" by anyone who wishes to do so. Its articles are not controlled or
copyrighted by any particular user or editorial group; decisions on the content and editorial policies of Wikipedia are instead made largely through
consensus decision-making and, occasionally, by vote.
Jimmy Wales retains final judgement on Wikipedia policies and user guidelines.
["Power structure", Meta-Wiki, 10:55 April 4, 2005]Regular users often maintain a "watchlist" of articles of interest to them, so that they can easily keep tabs on all recent changes to those articles, including new updates, discussions, and vandalism. Most past edits to Wikipedia articles also remain viewable after the fact, and are stored on "edit history" pages sorted chronologically, making it possible to see former versions of any page at any time. The only exceptions are the entire histories of articles that have been deleted, and many individual edits that contain
libelous statements, copyright violations, and other content that could incur legal liability or be otherwise detrimental to Wikipedia; these edits may only be viewed by Wikipedia administrators.

Wikipedia originally developed out of another encyclopedia project, Nupedia. |
The Wikipedia concept was not novel —
Everything2 (in 1998-1999) had used the same ideas before Wikipedia was founded — and Wikipedia began as a complementary project for
Nupedia, a free online encyclopedia project whose articles were written by experts through a formal process. Nupedia was founded on
March 9,
2000 under the ownership of
Bomis, Inc, a Web portal company. Its principal figures were
Jimmy Wales, Bomis
CEO, and
Larry Sanger,
editor-in-chief for Nupedia and later Wikipedia. Nupedia was described by Sanger as differing from existing encyclopedias in being
open content, in not having size limitations, due to being on the
Internet, and in being free of bias, due to its public nature and potentially broad base of contributors.
[Larry Sanger, "Q & A about Nupedia", Nupedia, March 2000] Nupedia had a seven-step review process by appointed subject-area experts, but later came to be viewed as too slow for producing a limited number of articles. Funded by Bomis, there were initial plans to recoup its investment by the use of advertisements.
It was initially licensed under its own Nupedia Open Content License, switching to the GFDL before Wikipedia's founding at the urging of
Richard Stallman.
On
January 10,
2001, Larry Sanger proposed on the Nupedia mailing list to create a wiki alongside Nupedia. Under the subject "Let's make a wiki", he wrote:
}}
Wikipedia was formally launched on
January 15,
2001, as a single English-language edition at http://www.wikipedia.com, and announced by Sanger on the Nupedia mailing list.
It had been, from January 10, a feature of Nupedia.com in which the public could write articles that could be incorporated into Nupedia after review. It was relaunched off-site after Nupedia's Advisory Board of subject experts disapproved of its production model.
Wikipedia thereafter operated as a standalone project without control from Nupedia. Its policy of "neutral point-of-view" was codified in its initial months, though it is similar to Nupedia's earlier "nonbias" policy. There were otherwise few rules initially. Wikipedia gained early contributors from Nupedia,
Slashdot postings, and
search engine indexing. It grew to approximately 20,000 articles, and 18 language editions, by the end of its first year. It had 26 language editions by the end of 2002, 46 by the end of 2003, and 161 by the end of 2004.
["Multilingual statistics", Wikipedia, March 30, 2005] Nupedia and Wikipedia coexisted until the former's servers went down, permanently, in 2003, and its text was incorporated into Wikipedia.

Wikipedia's English edition on March 30, 2001, two and a half months after its founding. |
Wales and Sanger attribute the concept of using a wiki to
Ward Cunningham's WikiWikiWeb or
Portland Pattern Repository. Wales mentioned that he heard the concept first from Jeremy Rosenfeld, an employee of Bomis who showed him the same wiki, in December 2000,
[Jimmy Wales, "Re: Sanger's memoirs", April 20, 2005,] but it was after Sanger heard of its existence in January 2001 from Ben Kovitz, a regular at the wiki,
that he proposed the creation of a wiki for Nupedia to Wales and Wikipedia's history started. Under a similar concept of free content, though not wiki-based production, the
GNUpedia project existed alongside Nupedia early in its history. It subsequently became inactive, and its creator,
free-software figure
Richard Stallman, lent his support to Wikipedia.
Citing fears of commercial advertising and lack of control in a perceived English-centric Wikipedia, users of the
Spanish Wikipedia forked from Wikipedia to create the
Enciclopedia Libre in February 2002. Later that year, Wales announced that Wikipedia would not display advertisements, and its website was moved to wikipedia.org. Various other projects have since forked from Wikipedia for editorial reasons, such as
Wikinfo, which abandoned "neutral point-of-view" in favor of multiple complementary articles written from a "sympathetic point-of-view".
The Wikimedia Foundation was created from Wikipedia and Nupedia on
June 20,
2003.
[Jimmy Wales: "Announcing Wikimedia Foundation", June 20, 2003, ] Wikipedia and its sister projects thereafter operated under this
non-profit organization. Wikipedia's first sister project, "In Memoriam: September 11 Wiki", was created in October 2002 to detail the
September 11, 2001 attacks;
[The "In Memoriam: September 11" site is not widely considered a "sister project" as of 2006; there has been calls to close the site, or move it to Wikia. "Proposals for closing projects", a page of the Wikimedia Meta-Wiki, discusses this process.] Wiktionary, a dictionary project, was launched in December 2002;
Wikiquote, a collection of quotations, a week after Wikimedia launched; and
Wikibooks, a collection of collaboratively-written free books, the next month. Wikimedia has since started a number of other projects, detailed below.
Wikipedia has traditionally measured its status by article count. In its first two years, it grew at a few hundred or fewer new articles per day; by 2004, this had accelerated to a total of 1,000 to 3,000 per day (counting all editions). The English Wikipedia reached its 100,000-article milestone on
January 22,
2003.
["Wikipedia, the free encyclopedia, reaches its 100,000th article", Wikimedia Foundation, January 21, 2003] Wikipedia reached its one millionth article, among the 105 language editions that existed at the time, on
September 20,
2004,
["Wikipedia Reaches One Million Articles", Wikimedia Foundation, September 20, 2004] while the English edition alone reached its 500,000th on
March 18,
2005.
["Wikipedia Publishes 500,000th English Article", Wikimedia Foundation, March 18, 2005] This figure had doubled less than a year later, with the millionth article in the English edition being created on
March 1,
2006["English Wikipedia Publishes Millionth Article", Wikimedia Foundation, March 1, 2006]; meanwhile, the millionth user registration had been made just two days before.
[Note that this user count includes both sockpuppets, accounts solely used for vandalism, and unused accounts. The number of true accounts is significantly less.]The Wikimedia Foundation applied to the
United States Patent and Trademark Office to
trademark Wikipedia® on
September 17,
2004. The mark was granted registration status on
January 10,
2006. Trademark protection was accorded by
Japan on
December 16,
2004 and in the
European Union on
January 20,
2005. Technically a
service mark, the scope of the mark is for: "Provision of
information in the field of general encyclopedic knowledge via the
Internet".
There are currently plans to license the usage of the Wikipedia trademark for some products, such as books or DVDs.

Wikipedia receives over 2000 page requests per second. More than 100 servers have been set up to handle the traffic. |
Wikipedia itself runs on its own in-house created software, known as
Mediawiki, a powerful
open source wiki system written in
PHP and built upon
MySQL. As well as allowing articles to be written, it includes a basic internal
macro language,
variables and
transcluded templating system for page enhancement, and features such as
redirection are also provided within the software.
Wikipedia runs on a cluster of dedicated
Linux servers located in
Florida and four other locations around the world. MediaWiki is Phase III of the program's software. Originally, Wikipedia ran on
UseModWiki by
Clifford Adams (Phase I). At first it required
camel case for links; later it was also possible to use double brackets. Wikipedia began running on a
PHP wiki engine with a
MySQL database in January 2002. This software, Phase II, was written specifically for the Wikipedia project by
Magnus Manske. Several rounds of modifications were made to improve performance in response to increased demand. Ultimately, the software was rewritten again, this time by Lee Daniel Crocker. Instituted in July 2002, this Phase III software was called MediaWiki. It was licensed under the
GNU General Public License and used by all Wikimedia projects.
Wikipedia was served from a single server until 2003, when the server setup was expanded into a distributed
multitier architecture. In January 2005, the project ran on 39 dedicated servers located in Florida. This configuration included a single master database server running
MySQL, multiple slave database servers, 21 web servers running the
Apache software, and seven
Squid cache servers. By September 2005, its server cluster had grown to around 100 servers in four locations around the world.
Page requests are processed by first passing to a front-end layer of
Squid caching servers. Requests that cannot be served from the Squid cache are sent to two load-balancing servers running the
Perlbal software, which then pass the request to one of the Apache web servers for page-rendering from the database. The web servers serve pages as requested, performing page rendering for all the Wikipedias. To increase speed further, rendered pages for anonymous users are cached in a filesystem until invalidated, allowing page rendering to be skipped entirely for most common page accesses. Wikimedia has begun building a global network of caching servers with the addition of three such servers in France. A new Dutch cluster is also online now. In spite of all this, Wikipedia page load times remain quite variable. The ongoing status of Wikipedia's website is posted by users at a
status page on
OpenFacts.
Wikipedia is funded through the
Wikimedia Foundation. Its 4th Quarter 2005 costs were $321,000
USD, with hardware making up almost 60% of the budget.
Bomis, an online advertising company that hosts mostly adult-oriented
web rings, played a significant part in the early development of Wikipedia and the network itself.
During December 2005, Wikipedia had about 27,000 users who made at least five edits that month; 17,000 of these active users worked on the English edition.
[Paragraph's statistics taken from "Active wikipedians" (Wikipedia Statistics, April 13, 2006).] A more active group of about 4,000 users made more than 100 edits per month, over half of these users having worked in the English edition. According to Wikimedia, one-quarter of Wikipedia's traffic comes from users without accounts, who are less likely to be editors.
["Wikipedia", Meta-Wiki, 08:02 March 30, 2005.]Maintenance tasks are performed by a group of volunteer developers, stewards, bureaucrats, and administrators, which number in the hundreds. Administrators are the largest such group, privileged with the ability to prevent articles from being edited, delete articles, or block users from editing in accordance with community policy. Many users have been temporarily or permanently blocked from editing Wikipedia. Vandalism or the minor infraction of policies may result in a warning or temporary block, while long-term or permanent blocks for prolonged and serious infractions are given by Jimmy Wales or, on its English edition, an elected Arbitration Committee.
Former Nupedia editor-in-chief, Larry Sanger, has said that having the GFDL license as a "guarantee of freedom is a strong motivation to work on a free encyclopedia."
[Larry Sanger, "Britannica or Nupedia? The Future of Free Encyclopedias", Kuro5hin, July 25, 2001.] In a study of Wikipedia as a community, economics professor Andrea Ciffolilli argued that the low
transaction costs of participating in
wiki software create a catalyst for collaborative development, and that a "creative construction" approach encourages participation.
[Andrea Ciffolilli, "Phantom authority, self-selective recruitment and retention of members in virtual communities: The case of Wikipedia", First Monday December 2003.] Wikipedia has been viewed as an experiment in a variety of
social,
political, and
economic systems, including
anarchy,
democracy, and
communism. Its founder has replied that it is not intended as one, though that is a consequence.
[Jimmy Wales, "Re: Illegitimate block", January 26, 2005, .] Critics of Wikipedia have also viewed it as an
oligarchy which is controlled primarily by its
administrators,
stewards, and
bureaucrats, or simply by a small number of its contributors.
Daniel Brandt of
Wikipedia Watch has referred to
Jimbo Wales as the "
dictator" of Wikipedia; however, most
Wikipedia users either do not consider Wales to be a dictator, or consider him to be
one who rarely gives non-negotiable orders.
Wikipedia has become increasingly controversial as it has gained prominence and popularity, with critics alleging that Wikipedia's open nature makes it unauthoritative and unreliable, that it exhibits severe
systemic bias and inconsistency, and that the
group dynamics of its community are hindering its goals. Wikipedia has also been criticized for its use of dubious sources, its disregard for credentials, and its vulnerability to vandalism and special interest groups [
1]. Critics of Wikipedia include Wikipedia editors themselves, ex-editors, representatives of other encyclopedias, and even subjects of articles.
It's been argued that Wikipedia should offer disclaimers on each page stating that entries are not written or reviewed by experts, and that no trust should inherently be placed in their accuracy.
At the end of 2005,
controversy arose after journalist
John Seigenthaler, Sr. found that his biography had been written largely as a hoax, which had gone undetected for almost 4 months; this led to several policy decisions within Wikimedia regarding creation of articles and the overview process, intended to address some of the flaws which had allowed the hoax to go undetected for that time.
The Wikipedia model
Wikipedia has been both praised and criticized for being open to editing by anyone. Proponents contend that open editing improves quality over time , while critics allege that non-expert editing undermines quality. Because contributors usually submit
edits, rewriting small portions of an entry rather than making full-length revisions, high- and low-quality content may be intermingled within an entry.
Wikipedia has been criticized for a perceived lack of reliability, comprehensiveness and authority. It is criticised as having no or limited utility as a
reference work among many
librarians,
academics, and the
editors of more formally written encyclopedias. Many university lecturers discourage their students from using any encyclopedia as a reference in academic work, preferring primary sources instead.
[Wide World of WIKIPEDIA] A critical website, Wikipedia Watch, was created by
Daniel Brandt to denounce Wikipedia as having "…a massive, unearned influence on what passes for reliable information."
[www.wikipedia-watch.org/]Some critics have suggested that Wikipedia cannot justifiably be called an "encyclopedia", a term which (it is claimed) implies a high degree of reliability and authority that Wikipedia, due to its open editorial policies, may not be able to maintain. However, Wikipedia does meet all the criteria for the basic definition of the word
encyclopedia. One difference from book encyclopedia is online web editing with wikipedia's history function. A deleted text will remain in the history tab and other users can look up an individual's work history to gauge the author's merit.
Emigh and Herring (2005)
[Emigh & Herring (2005) ''Collaborative Authoring on the Web:A Genre Analysis of Online Encyclopedias'', Proceedings of the Thirty-Eighth Hawai'i International Conference on System Sciences. (PDF)]in a study of Wikipedia, note that there are not yet many formal studies of Wikipedia or its model. Their main conclusions regarding style and encyclopedic quality were:# Statistically speaking, "the language of Wikipedia entries is as formal as that in the traditional print encyclopedia".# Wikipedia entries are "stylistically homogenous, typically describe only a single, core sense of an item, and are often presented in a standard format" (attributed partly to policies and partly to the norms of conventional print encyclopedias "which Wikipedia effectively emulates")# Wikipedia achieves its results by social means, including
self-norming, a core of active and vigilant users watching for problems, and editors' expectations of encyclopedic text drawn from the wider culture.
Reliability
Wikipedia can be assessed for reliability in several areas, including::* Accuracy of information provided within articles:* Comprehensiveness, scope and coverage within articles and in the range of articles:* Susceptibility to, and exclusion and removal of, false information (a criteria specific to the Wikipedia process):* Susceptibility to editorial and systemic
bias:* Identification of reputable third party source references (citations)
Accuracy and comprehensiveness
A variety of studies to date have tended to suggest that Wikipedia is of a similar order of accuracy to
Encyclopædia Britannica, provides a good starting point for research, and that articles are in general reasonably sound, but that due to its novel editorial model, it suffers omissions and inaccuracies and sometimes these can be serious. A separate study suggests that in many cases, vandalism is reverted fairly quickly, but that this does not always happen. One of the studies, by
Nature, identified that Wikipedia and Encyclopædia Britannica had a comparable level both of serious errors (4 and 4 respectively in 42 articles) and also of lesser errors and omissions (162 and 123 respectively).
Critics of Wikipedia often charge that allowing anyone to edit makes Wikipedia an unreliable work, and that some editors may employ clever use of semantics to make possibly biased statements sound more credible.[
2] Wikipedia contains no formal
peer review process for fact-checking, and the editors themselves may not be well-versed in the topics they write about, leading to criticism that its contents lack authority,
[Simon Waldman, "Who knows?", The Guardian, October 26, 2004.] and that "[i]t will never be an encyclopedia, but it will contain extensive knowledge that is quite valuable for different purposes."
[Danah Boyd, "Academia and Wikipedia", Many-to-Many, January 4, 2005.] Although Wikipedia has a policy of citing primary sources, this is only sometimes adhered to.
Encyclopædia Britannica's executive editor, Ted Pappas, was quoted in
The Guardian as saying: "The premise of Wikipedia is that continuous improvement will lead to perfection. That premise is completely unproven."
and former
Britannica editor
Robert McHenry criticized the wiki approach on the grounds that "What [a user] certainly does not know is who has used the facilities before him."
[Robert McHenry, "The Faith-Based Encyclopedia", Tech Central Station, November 15, 2004.]Academic circles have not been exclusively dismissive of Wikipedia as a reference. Wikipedia articles have been referenced in "enhanced perspectives" provided on-line in
Science. The first of these perspectives to provide a hyperlink to Wikipedia was "A White Collar Protein Senses Blue Light",
[ (subscription access only)] and dozens of enhanced perspectives have provided such links since then. However, these links are offered as background sources for the reader, not as sources used by the writer, and the "enhanced perspectives" are not intended to serve as reference material themselves.
Former Nupedia editor-in-chief Larry Sanger criticized Wikipedia in late 2004 for having, according to Sanger, an "anti-elitist" philosophy of active contempt for
expertise.
[Larry Sanger, "Why Wikipedia Must Jettison Its Anti-Elitism", Kuro5hin, December 31, 2004.] It is possible that articles subject to strong opinions (such as
George W. Bush) are more prone to be edited poorly, but this is uncertain - often such articles receive extra attention and strong consensus exactly because they are the subject of heated debate. Other articles that do not produce such emotive responses may tend to be more stable.
Other commentators have drawn a middle ground, that it contains much valuable knowledge and has some reliability, even if the degree is not yet assessed with certainty. People taking such a view include
Danah Boyd ("[i]t will never be an encyclopedia, but it will contain extensive knowledge that is quite valuable for different purposes"
[Danah Boyd, "Academia and Wikipedia", Many-to-Many, January 4, 2005.]),
Larry Sanger ("Given enough eyeballs, all errors are shallow"
["Wikipedia is wide open. Why is it growing so fast? Why isn't it full of nonsense?", September 24, 2001.]) and technology figure
Joi Ito, who wrote, "the question is whether something is more likely to be true coming from a source whose resume sounds authoritative or a source that has been viewed by hundreds of thousands of people (with the ability to comment) and has survived."
[Joi Ito, "Wikipedia attacked by ignorant reporter", Joi Ito's Web, August 29, 2004.]Bill Thompson, a well known technology writer, commented that the debate is probably symptomatic of much learning about information which is happening in society today, arguing that:
Coverage
A common criticism is that editors, being volunteers, write on what interests them, and what they are aware of. Therefore coverage both within topics, and across the encyclopedia, is uneven and may at times be seriously unbalanced, with obvious and notable omissions. This was identified as a common flaw by some studies.
Wikipedia has been accused of deficiencies in comprehensiveness because of its voluntary nature, and of reflecting the systemic biases of its contributors. For example, like any internet group, the site can become dominated by cliques of habitual users who express both condescension and hostility to users not involved in the "in-group" — habitual users also feel a sense of "ownership" over "their" pages, leading to edit wars.
Encyclopædia Britannica's editor-in-chief Dale Hoiberg has argued this case,
as has former Nupedia editor-in-chief Larry Sanger who stated in 2004 that "when it comes to relatively specialized topics (outside of the interests of most of the contributors), the project's credibility is very uneven."
|
"Be Bold" has become an unofficial slogan of Wikipedia. |
The same fluidity that allows articles to be patchy has also led to Wikipedia being praised for making it possible for articles to be updated or created in response to current events. For example, the then-new article on the
2004 Indian Ocean earthquake on its English edition was cited often by the press shortly after the incident.
[Cited by Workers World (January 8, 2005) and Chicago Times (January 16, 2005)] Its editors have also argued that, as a website, Wikipedia is able to include articles on a greater number of subjects than print encyclopedias may.
["Wikipedia:Replies to common objections", Wikipedia, 22:53 April 13, 2005.]Community
The
Wikipedia community consists of users who are proportionally few, but highly active. Emigh and Herring argue
that "a few active users, when acting in concert with established norms within an open editing system, can achieve ultimate control over the content produced within the system, literally erasing diversity, controversy, and inconsistency, and homogenizing contributors' voices."
Editors on
Wikinfo, a
fork of Wikipedia, similarly argue that new or controversial editors to Wikipedia are often unjustly labeled "
trolls" or "problem users" and blocked from editing.
["Critical views of Wikipedia", Wikinfo, 07:28 March 30, 2005.] Its community has also been criticized for responding to complaints regarding an article's quality by advising the complainer to fix the article (a common complaint about
open-source software development as well).
[Andrew Orlowski, "Wiki-fiddlers defend Clever Big Book", The Register, July 23, 2004.] It has also been described as "cult-like",
although, as these instances demonstrate, not always with entirely negative connotations.
In a page on , the community view is argued that Wikipedia is valuable for being a social community. That is, authors can be asked to defend or clarify their work, and disputes are readily seen.
["Wikipedia:Researching with Wikipedia", Wikipedia (March 28, 2005).] Wikipedia editions also often contain
reference desks in which the community answers questions.
Network reliability

Wikipedia's default notice for unforseen downtime |
The English-language website at times also suffers from frequent timeouts, server errors and occasional
downtime due to heavy user traffic. These problems have had a negative effect on Wikipedia's desired image as a fast and reliable source of information.
Responses to criticisms
In an
interview with
BusinessWeek on
December 13, Wales discussed the reasons that the Seigenthaler hoax had gone undetected, and steps being taken to address them. He stated that one problem was that Wikipedia's use had grown faster than its self-monitoring system could comfortably handle, and that therefore new page creation would be deliberately restricted to account-holders only, addressing one of Seigenthaler's main criticisms. He also gave his opinion that encyclopedias as a whole (whether print or online) were not usually appropriate for primary sources and should not be relied upon as authoritative (as some were doing), but that nonetheless on balance Wikipedia was more reliable as "background reading" on subjects than most online sources. He stated that Wikipedia was a "work in progress".
[ Wikipedia: "A Work in Progress" December 14, 2005 ]In response to this criticism, proposals have been made to provide various forms of provenance for material in Wikipedia articles.
["Wikipedia:Provenance", Wikipedia (May 9, 2006).] The idea is to provide
source provenance on each interval of text in an article and
temporal provenance as to its vintage. In this way a reader can know "who has used the facilities before him" and how long the community has had to process the information in an article to provide calibration on the "sense of security". However, these proposals for provenance are quite controversial. Aaron Krowne wrote a rebuttal article in which he criticized McHenry's methods, and labeled them "
FUD", the marketing technique of "fear, uncertainty, and doubt".
[Aaron Krowne, "The FUD-based Encyclopedia", Free Software Magazine, March 1, 2005.]Wikipedia won two major awards in May 2004:
["Trophy Box", Meta-Wiki (March 28, 2005).] The first was a Golden Nica for Digital Communities, awarded by
Prix Ars Electronica; this came with a
EU€10,000 grant and an invitation to present at the PAE Cyberarts Festival in
Austria later that year. The second was a Judges'
Webby award for the "community" category. Wikipedia was also nominated for a "Best Practices" Webby. In September 2004, the
Japanese Wikipedia was awarded a Web Creation Award from the Japan Advertisers Association. This award, normally given to individuals for great contributions to the Web in Japanese, was accepted by a long-standing contributor on behalf of the project.Wikipedia has received plaudits from sources including
