I'm on Quora and I like it there, although I visit with decreasing frequency. I think they are trying to emulate more of a Twitter/Facebook thing with their user base - a more "social" experience than stackoverflow, I guess - and I assume their monetization strategy is as undefined as it was for either of those two when they started.
