I use the Ubuntu, Unix/Linux, LaTeX, Math and Statistics stack exchange sites regularly and they have helped me tremendously in achieving a lot of stuff that would probably have taken me much more time to figure out by myself. I think most sites will quiet down with time, because once all questions have been asked there won't be as much interest, but they will always stay my number one source of information because in one swoop I can : * Check if a question was asked on the topic I am looking for. The Ask Question page will do a search for you after you're done typing your question title. * If not, ask the question, and most of the time in asking the question I solve my own problem. * If problem not solved, wait for suggestions/answers. The difference between this and forums or mailing lists is that the rating of answers allows you to pick out quickly the best and most approved answers. I agree with the other comment here in that not all subjects are proper to a stack exchange site, they are clearly not the best medium to do discussions for various reasons: the ordering of answers is not preserved, you cannot start a sub-thread other than by doing comments, you cannot reply to a specific comment, etc.
