Well, in my eye, I see myself as an artist/game designer, so when I look online to see and learn, there are two sites in particular that I have always garnered to. The first, gamasutra.com is a site that really breaks almost all of the industry down, there is information to the coders, sound board guys, the artists, and the designers. I did summarize most of the jobs, because there are many others that would be included into the creation of a game. But gamasutra will cover your needs when discussing the post mortems, to the creative board and how to keep your interest into what you are doing.

The second one that I have as one of my homepages has been game-artists.net. I don't frequent this site as much as I would of liked to in the past year, mostly because knowing my issues with 3d art, I focused on the traditional art, improving on my anatomy and shadowing skills. But this site holds many fine artists, that work in the industry and outside of the industry, they have keen eyes to help you to see things more clearly and where to improve. A big props to the site and the fellows that run it, for they do competitions that range from concept art, to speed modeling.

I forgot to mention another one that I do frequent, though getting response on it is sometimes flaky, would be deviantart.com. Can spend mass amounts of time looking at other peoples art and can get inspired by quite a few of the pieces there.
