I agree with you about the importance of framing, but I think there's more than that going on here. For one thing, Jaron's essay seems to address a completely orthogonal (and frankly, fairly silly) question: is it safe to allow a "collective", as opposed to individual people, say things?

As for Sanger, I think his latest actions show that he doesn't agree with my core point. If Sanger believed the masses were the experts, then he wouldn't be banning anonymous editing in his new Citizendium. But while we agree on the goal -- making a high-quality, free encyclopedia -- Sanger's disagreement on the facts is leading him in the opposite direction.
