What Is Quora’s Biggest Challenge?

much like plancast, i think quora is a great idea, but one that could struggle outside of the valley.

i think quora should consider certain barriers to contribution like ones that wikipedia has in place.

if they focus on establishing a resource (rather than a social network ... e.g. pts, etc), i think they have serious sustainability potential. if the emphasis is placed on the leaderboard, many will try to game the system and compromise the inputs.
