I approve of Citizendium. More free content is a win for everyone in the world, and there’s got to be more than one way to do this wiki-based encyclopedia thing. The people are good and thoughtful and the community is enthusiastic.
However, Sage Ross notes that the edit rate is going down, suggesting it’s failing to reach critical mass. (He doesn’t give numbers, nor does CZ:Statistics, though Citizendium does have a graph of active users in each month.) He has a draft article for the Signpost.
Citizendium still hasn’t picked a licence for those articles not originally from Wikipedia. Some editors seem to want to clean all Wikipedia prose out of Citizendium articles; I can’t say this is a bad idea, in that it would free them from the GFDL, which is a horrible licence for a wiki. (The first Creative Commons licences weren’t out yet when Wikipedia started.)
On Citizendium’s Alexa daily reach chart, you can see the bursts of publicity. Publicity gets viewers and presumably editors, then the rate tapers off. Mike Johnson has previously noted that criticising Wikipedia is the quick way to publicity for Citizendium, though doing so just for publicity would be distasteful. And would distract from writing an encyclopedia. What else can be done to lure people to it? (I have a login but I think I’ve made two edits … I barely edit Wikipedia of late.) Many people like the idea of a participatory encyclopedia, but have a strong distaste for the more obnoxious bits of the English Wikipedia community – but do they actually then write anything on Citizendium? Or anywhere else?
