I've burnt up hundreds of hours in groups.google.com, but less so as I learn more and more. GG is definitely the best place for new developers. Second I'd say is the MSDN newsgroups and MSDN forums.
My big problem with Koders is that it emphasizes cut-and-paste coding, whereas the forums and groups emphasize the "how do I do this?" "use this pattern" dynamic. Cut and paste should be considered harmful. If you don't understand the code you're pasing you do no good.
