If there's anything I hope to be, it's a student. StackOverflow appeals to me in the same way Slashdot once did: it's a constant stream of new terminology I can almost, but not quite, understand. As I acquire mastery in one area, a new item of interest begins inspiring questions and further opportunities to learn.
The majority of questions that I answer, I look up the answers and learn the subject with the asker. This may make my information inexpert on occasion, but it means I always check my work for correctness and often provide references that I used to research.
