brickfilms.com used to be pretty happenin', but I heard it crashed.

Also, you could check out the Brickfilm wiki.

Other than that, unless you go to a production company's website, such as http://www.aardman.com/, there aren't that many other stop-motion focused sites out there that I know of, anyway.

Have you tried a basic search engine? A quick search turned up the following:
http://www.stopmotionanimation.com
https://stopmotionexplosion.com
There's also stopmotionmagazine.net which has a free magazine downloadable in PDF. I met the guy who does the site at Gumbyfest a couple years ago, he did a talk on 3D printing and showed me his setup, which I promptly went out and got a used one. Anyway, point of the story is he's a cool dude.

There's a bunch of links to brickfilming and stopmotion sites on the links section of the Brickfilmer's Guild.
