The mod vs. unmodded issue is a classical problem on the internet, and may never be solved fully. I don't think SO's modding is any worse than Wikipedia's. As such, both are good enough.

I agree, it isn't any worse than one of the biggest examples of biased, overzealous, insular, clique moderation online. I think setting our standards a little higher than that is pretty reasonable though.
