I hate to say this, since it is our own dog food, but it's incredibly hard to find useful, timely information in both the forums and the groups. If I cannot find my answer in the structured documents (which are for the most part great), or in the code myself, I try Google against the whole web next.
Whether they are "intended" to work this way or not, the Forums (and to a lesser degree, the Groups) actually serve this kind of purpose very well. The Forums are always my first stop, and often my last. If I had a major say in any restructuring of the Drupal cosmos, I would try to centralize the Forums and Groups in peoples' minds, and make much better use of taxonomy on d.o.
