Origin XT Network
A great community that helped fuel my internetism. The members are quirky, and the staff is eccentric, but it's easy to feel right at home. Or maybe I'm just weird, too.

The first sprite comic, containing the epitome of spriting awesomeness. Also contains the MS-Paint Masterpiece, my favorite BnG-inspired spritecomic.
The prefix wiki- is growing old already, but this website is too amazing to pass up. It is an enyclopedia with definitions to anything you'd ever want.
If you're into open source, then I doubt there's a better website you can find. You can find programs and internet applications for virtually anything. A definite must-see.
Have a good website? Want it in the links? E-mail me, and I'll review your website.
