http://stackoverflow.com/ http://news.ycombinator.com/ and the usual mailing lists.
The CodeProject.com is my main resource, as well as just plain doing a Google Search. I also occasionally use Iconlet.com.
Codeproject, Codeguru, MSDN, etc
I don't visit any.
Just mainly use Google and go to what ever it finds.
CodeProject.net, AskExperts.com, and pretty much wherever Google takes me.

Ajaxian.com, Slashdot.org, TheDailyWTF.com
