Here are a bunch of other websites. None of them are this website, but try not to hold that against them.

Gaming:

Wizards.com: Although frankly, if you don't know this site, why are you reading about D&D in the first place?

RPGA: The Role-Playing Game Association, and home organization that publishes the Polyhedron email newsletter.

The System Reference Document: The SRD is the core of the d20 rules, in case you didn't know.

The Hypertext SRD: The entire SRD, hyperlinked in HTML for your online convenience.

Message Boards:

Wizards.com Message Boards: Where the legend of Giant in the Playground began...

EN World Message Boards: You probably know this one too...as much d20 than D&D, and a lot of 3rd Party influence.

3rdEdition.org: A great site with reviews and advice articles.

DnD Resources.com: A nice site of homebrew resources and weblinks to other places.

Webcomics/Humor:
