Pal, I think you are already at the right place.

I strongly second that. Communities and discussions do not substitute books, but are important. As I've written several times, I've learnt more from clpmisc than from anywhere else. My first questions were very naive, but I got to appreciate the community. It is somewhat harsher than here, but I have no problem with that as long as it keeps the quality of discussions high; also beacuse its behavioural rule are just out of common sense after all. I discovered PerlMonks later, but the same remarks apply more or less unchanged. All in all they are not in competition, but constitute complementary resources, both in philosophy and partecipating people, out of many others, of course.
