Ah, now how does one find the sweet spot between this and say Stack Exchange? Many times, I have heard users complain about the barrier for Stack Exchange and overzealous moderators. There is not really a way to please everyone.

I never really understood how moderation works on Quora so I assumed there was none. Not to say that I hate Quora (I like it a lot), I just feel there is nothing preventing it from becoming Yahoo Answers in a couple years time. No barrier, no moderation.
