Just as I thought it would, Wikipedia will fork. Larry Sanger, co-founder of Wikipedia, will start a version of Wikipedia, called The Citizendium Project. This version, which he announced in March 2005 here will start its life as a mirror of Wikipedia’s current content, but will then allow ‘experts’ to modify the original content of Wikipedia. In some way, I like to consider Jahsonic as a forked  version of Wikipedia too.

Wikipedia has this.
