List of Generalizations of Common Questions

There was a question posted just now asking why $0!=1$ which I dutifully answered. But one of the comments noted that the same question had been asked three times before. Aside from keeping records, if people are asking the same questions over again, might it be worth having a FAQ section for those questions which come up, say, three times or more?

Especially at the beginning of the Academic Year, it is likely that similar questions will arise. Note also that the recent and forthcoming posts on Gowers' blog may be a useful source of reference.
