Here's a list of the animation Blogs that I read:
http://sewardstreet.com/ Fellow animator at Dreamworks. He has a good sense of what's going on in Animation.
http://manuittina.com/blog.html Another Fellow animator at Dreamworks. He is starting to put together a lot of good resources on his website.
http://cganimation.blogspot.com/ This Blog is written anonymously so that he can post his true feelings about the animation business.
http://james-baker.com/news/ Jamie Baker's Blog, this one is new to me, but it looks like it has some promise.
http://www.bitterfilms.com/forum.html Not really a blog, more of a production journal. I love Don Hertzfeldt's films, reading his journal entrys are every bit as entertaining as his films!
http://www.plymptoons.com/scrapbook/scrap092704.html Bill Plymton has some good entrys on his film making experience. His website is a great resource for indipendindent film making.
http://www.ronniedelcarmen.com/blog1/blog.html Ooo, pretty drawings.
http://pixaranimation.blogspot.com/ This is maily a Fanboy Blog about Pixar, but it does have some good news resources.
Not really blogs, but animation news resources:
http://www.cartoonbrew.com/ This is a great cartoon news source. The guys who write this often have a good eye as to what's cool about animation.
http://www.animated-news.com/ Another good news source for the business.
http://www.jimhillmedia.com/ A former Disney Animator, Jim Hill Media has good commentary about the goings on at Disney.
http://www.zayatz.com/ This isn't a Blog, or a news source, but it has a lot of good information in it for up an coming animators.
If you know of more, I'd love to hear them.
