I'm under 100. I love Stack Overflow, but the reason that my reputation is so low is that when I'm in software development mode, I'm usually so busy working that I don't have the time to (nor rarely think about) go back and answer some questions. Maybe one of these days when I have the time to step back and think about software development outside the context of a project, I'll go back and chip in. God knows I use it often enough every day.
