I would be hard pressed to find a site that required serious development effort and did not collect and sell your information. In this case though, they're mainly collecting your interests, subjects you follow, answers on subjects, how others rated those answers, and your questions. Not exactly private stuff unless you're interested in crazy subjects. They also have an anonymous option, where you can answer anonymously. I'm not sure how that will be sold, Quora still knows who you are, answered as anonymous vs not would be useful information.
