Wikipedia
Larry Sanger and Jimmy Wales are the ones who started Wikipedia. Wales is credited with defining the goals of the project. Sanger created the strategy of using a wiki to reach Wales' goal. On January 10, 2001, Larry Sanger proposed on the Nupedia mailing list to create a wiki as a "feeder" project for Nupedia. Wikipedia was launched on January 15, 2001. It was launched as an English-language edition at www.wikipedia.com, and announced by Sanger on the Nupedia mailing list. Wikipedia's policy of "neutral point-of-view" was enforced in its initial months and was similar to Nupedia's earlier "nonbiased" policy. Otherwise, there weren't very many rules initially, and Wikipedia operated independently of Nupedia.
