This question already has an answer here:
I started really programming 94 days using Mathematica. I learned with 2 friends and SO. I asked 74 questions yet all answered with generosity.
Sometimes I feel guilty only "asking". Then I thought that it depends on what others do.
I would be greatly interested to see some data of users behavior in that regard. From always asking to always answering, how are users distributed? This, along with data on time spent on SO, votes attributed, etc.
I would then like to see how that compare to Wikipedia Editors/Readers statistics.
