criticism of Wikipedia

Two radically different versions of the Wikipedia article on Klee Irwin (now deleted) presented to the public within days of each other: Wikipedia's susceptibility to edit wars and bias is an issue often raised by the project's critics.

Wikipedia has been criticized since it was created in 2001. Most of the criticism has been directed toward its content, community of volunteer editors, process, and rules. Critics have questioned its factual reliability, the readability and organization of its articles, the lack of methodical fact-checking, and its political bias.
