Network effects create counterintuitive situations. If you pick a random one of your friends, that person probably has more friends than you do (this is true! for most values of "you" at least). I bet that it's likewise true that when you ask someone a question, it will usually be the case that that person answers more questions than you do (again, for most values of "you"). I think the distribution of how many questions a person is asked is very nonlinear. Someone who answers five questions a week is going to have a very different experience, and want very different social norms, than someone who answers fifty, or a hundred and fifty.
