Hackernews and various blogs, feeds.
I subscribe to a few mailing lists, but mainly I google.
Mostly just stackoverflow.com
I like to help answer questions on the Adobe community forums.
stack overflow is a very useful resource, linuxforums for my Linux issues. The register because, well, you have to. Other than that I causally read a large number of tech sites and pay little attention to what they are called (techRadar I think is one, wired maybe (that might not be tech stuff)). I'm a big fan of ashlee vance, I've tried to follow him since his register days. I often catch stuff on Feeding edge, which is run by an ex-IBMer.
No regular habit.
Stack overflow, techmeme, Reddit
It use to be XNA-UK UG, but as we have had to close it, none now really.. :(
