But honestly, it's better to give than to receive. (Yes, crazies, this quote "has its roots in religious scripture", but that's light years away from my point.)
Teaching someone else is, I think, one of the best ways to organize your own knowledge about the subject. And, if Schoolhouse Rock has taught us nothing, it's taught us: "Knowledge is power!"
Giving something back is important, especially for us older guys who got help from others earlier.
I also see many of the questions as puzzles to solve, instead of doing crosswords or a sudoku. Being able to solve it is nice in itself.
Reputation. It is the only other thing I can think of ... Ohh, and more experience trouble shooting 8 ^ )
For me it's pleasure. I love helping others and knowing that I helped someone, even if complete stranger, makes me feel good from the inside.
The reputation is nice addition of course and act as "positive feedback" all along, reassuring me that I'm doing it properly.
And the side effect is widening my own horizons - for example without being active here I'd never use jQuery as extensively as I'm using it these days.
