Social networking features recommendation for this task force

Just want to echo my support for this. I think social networking could attract a different kind of user. That said, there is a dark side to social networking (harassment, organizing angry mobs). But I'm going to try to think hard about ways to contain those, or at least address abuse after the fact.

I'm willing to accept that objections shouldn't block this proposal -- only force this proposal to be the best design we can think of.
