There has been a lot of brou-ha-ha as of late over the Wikipedia and how it's run and I haven't pointed to any of it because my assumption has been that it will eventually work itself out (as many problems in the social medium often do). To that end, I thought this report from Nicholas Carr was significant:
The man who invented Wikipedia now wants to bury it. Larry Sanger, the controversial online encyclopedia's cofounder and leading apostate, announced yesterday, at a conference in Berlin, that he is spearheading the launch of a competitor to Wikipedia called The Citizendium. Sanger describes it as "an experimental new wiki project that combines public participation with gentle expert guidance." The Citizendium will begin as a "fork" of Wikipedia, taking all of Wikipedia's current articles and then editing them under a new model that differs substantially from the model used by what Sanger calls the "arguably dysfunctional" Wikipedia community.
