" There are billions of people looking for just the type of answers you find on Quora"
And how many of them are going there? Every indication is "not many".
"Also you go to S.O. to find a specific answer than move on, on Q you stick around and read other stuff, go back for discovery."
By "you" you mean?
I've visited quora maybe a dozen times, usually by following a link from an aggregator like HN. I didn't feel compelled to poke around once I got there, and the comments and replies (though they came from the people with higher reputation) generally ran the same gamut as everywhere else.
