In March 2010, about 90 people made even a single edit to Citizendium. Compare Conservapedia, which has 76 in the last week at the time I write this. The difference is, the latter is pretty much a personal website run by a gibbering fundie lunatic which gets pretty much all its traffic from sceptics making fun of it; the former was a serious project.
This is terribly sad. What went wrong?
