cupidio writes: Ars Technica is running a feature on Citizendium, the new wiki-based encyclopedia started by Wikipedia co-founder Larry Sanger. One interesting revelation is that Sanger started work on the project only after talking with John Seigenthaler, victim of a famous Wikipedia hoax that accused him of murder. "When Seigenthaler called, I was already resigned to the necessity of making a competitor to Wikipedia," Sanger says. "The effect of Seigenthaler's call was to make me feel to some extent personally responsible for the injustice that Wikipedia was causing, which made my motivation only stronger. When after six to nine months I saw that Wikipedia wasn't going to make any significant changes, it became clear that it was on me to organize a better alternative, if I could." Can Citizendium get bigger than Wikipedia?
