What's the goal of this site? I'm not sure I'd want to ask someone a question that they may have already read the answer to. When I interview someone, I want to know what they actually know or can figure out with hints, not whether they have Googled for the right list of questions.

Edit: oh, even worse, it tags them by the company that asks the question. Great. I'm sure those companies will appreciate having to come up with brand new questions for each candidate. And candidates will really be better off getting in based on memorized answers, then finding themselves unable to solve the actual problems in the job. (sarcasm)
