If you read a Wikipedia article about Wikipedia, does the internet fold up into itself? Can God make a Wikipedia article so contentious that not even God could edit it?
Wikipedia (i/ˌwɪkɨˈpiːdiə/ or i/ˌwɪkiˈpiːdiə/ wik-i-pee-dee-ə) is a collaboratively edited, multilingual, free-access, free content Internet encyclopedia that is supported and hosted by the non-profit Wikimedia Foundation. Volunteersworldwide collaboratively write Wikipedia's 30 million articles in 287 languages, including over 4.5 million in the English Wikipedia. Anyone who can access the site can edit almost any of its articles, which collectively make up the Internet'slargest and most popular general reference work. In February 2014, The New York Times reported that Wikipedia is ranked fifth globally among all websites stating, "With 18 billion page views and nearly 500 million unique visitors a month..., Wikipedia trails just Yahoo, Facebook, Microsoft and Google, the largest with 1.2 billion unique visitors."
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001, the latter creating its name, aportmanteau of wiki (the name of a type of collaborative website, from the Hawaiian word for "quick") andencyclopedia.
Wikipedia's departure from the expert-driven approach to encyclopedia-building and the presence of much unacademic content have received extensive media attention. In 2006, Time magazine recognised Wikipedia's participation (along with YouTube, Reddit, MySpace, and Facebook) in the rapid growth of online collaboration and interaction by millions of people worldwide. Wikipedia has also earned a reputation as a news source because of its rapid updating of articles related to breaking news.
Wikipedia's open nature has led to various concerns, such as the quality of its writing, vandalism and the accuracy of its information. However, while some articles contain unverified or inconsistent information, a 2005 survey of Wikipedia published in Nature based on a comparison of 42 science articles with Encyclopædia Britannica found that Wikipedia's level of accuracy approached Encyclopædia Britannica's and both had a comparable rate of "serious errors". As of 2014, Wikipedia contains nearly five million articles, more than one hundred times Britannica's article count of 40,000 articles. Wikipedia's policies include verifiability and a growing body of standards for quality assurance.
