I see a lot of comments about how Quora is only providing value or attracting users in the valley and while I hate anecdotal premises that are used as support for arguments, I live in the midwest and over three quarters of my friends use Quora on a daily basis. I don't see it as a direct competitor to Facebook or Stackoverflow, but instead as filling a niche unto itself. I can't speak to the value it adds for all subject matter categories, but for the ones that I am most interested in (startup entrepreneurship, technology, mathematics) it has some incredibly thought-provoking questions and answers. The biggest value that I get from Quora is not when I am looking for a specific answer, but the serendipity of scrolling through my favorite topics to find questions that I wouldn't have thought to ask. If Quora died, it would be a sad day for the world's intellectual curious.
