Really interesting idea. Off topic a bit, but I've been thinking that comment moderation really needs an overhaul. It seems like more sophisticated algorithms could be used (is number of upvotes really the best we can do?). I think of weighted upvotes (obviously) as well as controlling for things like time visible and number of views. It seems to me that moderation could be made almost fully automatic - with just a bit of oversight perhaps to confirm judgement (weighing) of sets of users. Isn't this just predictive analytics being applied to those who view comments?
