What Citizendium's Homeopathy article shows more than anything is that a wide base of editors, and therefore a wide audience, is essential for the success of Wikipedia or any similar project. The article shows a distinct lack of the cleansing effects of sunlight; few people read it, few people contribute to it, and it's become the home of fringe POV editors who have tried and failed to sling the same on Wikipedia. Citizendium might do better if it made a more concerted attempt to discern between actual experts in fact and self-described experts in name only, but they apparently have chosen not to do that or don't have enough people from which to pick.
I say, let them congregate on Citizendium. We should have a template {{trycitizendium}} that we can post on the pages of our more aggressive POV pushers.
