Since you're in SF though, have you thought about holding a small group discussion about it over at noisebridge sometime? People there are always so insightful, friendly and willing to help, I'm thinking that holding a think-tank at a place like that might help you get the sort of 'back-and-forth' feedback it seems you're looking for.
Noisebridge is cool, hung out there a few times. I'm super busy now but maybe in a week or two though I am a sucker for coffee chats (hint hint). Basically I suck at writing and would rather connect through any other medium.
Also to add a few details, I'm doing this as a startup (Tagbax, don't mind the landing page, I'm really not trying to drive traffic yet). Community comment moderation isn't necessarily my first choice to apply the tech $ wise (I really ought to drop by disqus one of these days), but it was designed specifically for user-generated content.
It's kinda like how people complain about how politics are only about soundbites. Sure, it's great to argue that among friends, but who really spends the time understanding the facts about every issue a candidate debates?
