What could be better than Wikipedia?

Word of two new challenges or opportunities for variations on Wikipedia, both found from visiting Michael's Blog. Here is Citizendium, supposedly going to be more expert? And here is Michael's post on the new Conservapedia, which calls itself a Christian alternative. I agree with Michael that Conservapedia's bristling about "anti-Christian" bias in Wikipedia based whether dates are given as CE versus AD is overboard.

More options can be good. I'm not yet convinced that either of these is better. I have not yet bookmarked either site or tagged them in Delicious.
