  4. Wikipedia is a Web-based free content encyclopedia openly edited and freely readable. It has 187 independent language editions sponsored by the non-profit Wikimedia Foundation. Entries on traditional encyclopedic topics exist alongside those on almanac, gazetteer and current events topics. Wikipedia is one of the most popular reference sites on the Web, receiving around 80 million hits per day.
    Wikipedia contains approximately 1.3 million articles, 470,000 of which are in its English language edition. It began as a complement to the expert-written Nupedia on 15 January 2001. It runs on wiki software, and has numerous sister projects such as Wiktionary and Wikibooks.
    Wikipedia has been praised for being free, being openly accessible, covering a wide range of topics, and being detailed. It has been criticized for lack of authority versus a traditional encyclopedia, systemic bias, and for deficiencies in traditional encyclopedic topics. It is also a large-scale experiment of a discourse as defined in social sciences: "an institutionalized way of thinking, a social boundary defining what can be said about a specific topic", in a global internet context of the early third millennium.
    The idea of a free, open community, united by technology, where the increasingly vast content is actively authored, reviewed and debated, all for public consumption makes the Wikipedia distinctive not only amongst encyclopedias but also informational resources in general. However, by its very nature of being open for anyone to edit, it is the responsibility of the individual editor and the Wikipedia community to be on constant guard against blatant acts of vandalism and lack of objective viewpoint. The credibility of Wikipedia has often come into question, because since anyone can edit that opens the door for a significant degree of poorly researched content and inaccuracy. Vandalism is a persistent problem, though to the community's credit is generally caught and reverted within minutes.
