Since all level questions are accepted, anyone can ask a question, but only those with training in statistics can answer. As I mentioned in my last question, I am very impressed with how quickly my questions are answered. And, I acknowledge the one-sidedness of my relationship with the community -- I ask questions. I don't have the skill to answer the vast majority of questions asked (and for those I could answer, most people on the site could answer it better).
So I am wondering: how is this site (and others, like math.SE) not entirely overrun with unanswered questions? There is a huge ratio of people trying to learn statistics to people at advanced levels. Is it that currently the site is more well-known among the high-level statistics community than the general public, so it creates a natural balance?
If this became commonplace in high school and colleges (e.g. listed as a default reference by teachers on syllabi) do you think the paradigm would break down? Is a certain ratio of skill levels of participants required to maintain constructive activity?
