I'm not sold that real-time is a feature you want in your social site.

Reddit has an issue with lightweight throwaway comments already. Broad mostly-right comments killing actual discussion.

Wouldn't adding real-time on top of that add up to the hell of teamspeak in games with a bunch of kids?

It could go like IRC... But if you're saying you're like Reddit, I don't see how it wouldn't devolve into pettyness.
