And so on. I don't so much spend a lot of time on forums (Matrix Games, Paradox, Wargamer's gaming sections are about it), but I do listen to a number of gaming podcasts. Three Moves Ahead, Games with Jobs, Idle Thumbs, Game Central and Jumping the Shark are all weekly listens.

I post on these forums/comment sections:
pcgamer.com
gog.com
bluesnews.com
nvnews.com
I used to post a lot on the Steam forums but they really pissed me off, so I stopped. I pretty much stopped posting on nvnews as well for many reasons, but I plan to randomly stop in from time to time. I randomly post a comment here and there on Destructoid, RockPaperShotgun and some other news outlets, as well as the Bioware forum.
I am considering joining the RPG Codex, though often think better of it and stop.
Gaming news sites I check everyday are:
RockPaperShotgun
PCGamer
Kotaku
Bluesnews
The ones I check once in a while:
Destructoid
GiantBomb
Joystiq
