Alright! From the top then!
1. WotC- Good Community, Loads of information, Official Errata, Official Game FAQs, and Board FAQs, Designers post there from time to time. Chats are always good, and they have special events.
2. Mortality.Net- d20 publishers and many publisher hosted forums. Mortality Radio, great interviews and contests at times. Kithmakers reviews alone are worth it.
3. Monte Cook- Great place to get to know Monte! I love things like his PrC workshop, Line of Site, and Rants.
4. Nutkinland- This place is just fun! They also have OT Forums!!! Definitly a place you can cut loose and just relax! Always nice.
5. Gamingreport.Com- Great news and articles. They sometimes get top scoops. I mostly head there for such.
6. GameWyrd- Terrific Reviews! While I know that normally reviews are a dime a dozen, his aren't IMHO.
7. Vahalla- They offer very wide variety of of forums. That's one of the reasons I like them so much! Multimedia, and the studio- a place where you can request custom graphics and post your artwork.
8. Pen and Paper- They offer news, Photo Gallery, Nice resource site over all.
Not quite paragraphs, but that's off the top of my head while chasing my kids.
