What totally pisses me off about Quora is their real name policy. I am blessed with a fairly rare name- surname combination, and I definitely don't want to give to anybody with google and a couple of hours of spare time the chance to build a complete record of my (possibly ever changing) interests, opinions and life anecdotes. Also the reason I use facebook as little as possible - never, basically. I just can't believe how others can be so fond of carving in stone and committing to eternity the result of their idle time and their fleeting thoughts about anything from food to politics to world peace, all carefully labelled and tagged for later retrieval and collection.
