Quora is alive and well, though certainly not uttered in the same breath as Facebook or
these days. In fact, even Quora has fielded the question,
"Is Quora overhyped?"
For a very brief time,
, created by a 17-year-old from Moscow, looked like it was going to be the next big thing in social media. The service -- which pairs Web-chatting users from all over the world anonymously -- failed to make it big with either investors or advertisers.
