I'm usually "trying to get something done", and I like smart people without a lot of BS (which is why I hang out here, even though there's the right kind of BS here, hehe!)
Anyway, the stackexchange.com sites are a very good resource for finding out stuff.
Not at all similar to here, where we value "personalities". Over there, it's strictly question and answer format.
The original, and the one I got started with is "stackoverflow", which is all about programming. But there are TONS of topics now. And there are often experts that seem to be just waiting to definitively answer a question. Of course anyone can answer a question, but unlike the typical non-moderated board, you don't have to sift through a bunch of nonsense to find the answer (or even if it HAS an answer). Each answer may be voted upon. The best answer gets up-voted, so that it's easy to concentrate on what you came to find out.
And it's kind of fun to go on there and answer a few questions yourself and gain some reputation points.
