The value of Quora, from my limited time using it, doesn't seem to be in the system so much as it is in the user base. I've seen answers authored by more founders/programmers/entrepreneurs from successful companies than I care to count. Facebook is going to suffer from a very fundamental flaw: its users are there to do two things: spy on their friends and play casual games. No one is logging into Facebook with the Google-esque "I'm trying to find something or help someone else find something" mentality. Quora's users are highly motivated and know why they are at Quora.com - to ask and answer questions. Interestingly, this is probably the same reason why Google will never succeed at social networking. Google has solidified itself in the minds of the public as the company who provides us with information when we want it, not the company who satisfies our voyeuristic desires. All this being said, as much as I rag on Reddit, I think they have Quora and Facebook beat as far as question/answers go. If someone could harvest that data and provide an interface that isn't as butt-fugly as Reddit they'd get some decent traffic.
