Non-serious version: I have an answer, I just can't find the right question ;-)
I've asked about 50-60 questions (mostly on StackOverflow). They were, for the most part, good questions that inspired excellent answers. I'm a somewhat intelligent long-time PhD student in computer science (well studied, well published, etc), so I feel that there are probably one or two questions (maybe even three) that I can help answering.
What process do you recommend that a question-only user go through to become a question-and-answer user? For example, I'm fairly well versed in C++. Should I monitor the C++ tag until I see questions that I can research and answer pretty well, or should I be hunting more specifically for questions that I'm already an expert on. Of course, I'm really only an expert on very specific areas of artificial intelligence and ad-hoc wireless networks, so I might have to search long and hard and probably on cstheory.
Hopefully this question is not too broad / trivial. I really respect and appreciate the SO community, and would like to do whatever I can to help it grow.
