I visit this site at least once a day, I think it's great because of the public forum and designers to sign up and find each other. It allows to link a network of designers closer.

This is the best design resource site ever!! They allow users to view all the news items from all the other design boards. Basically once you get here, you won't need to go to the other ones.

This is cool too, there are many designer profiles that are very interesting, as well as interviews that are very worth your time to read.

Another design portal that is way worth a visit.

This is one of the first design portals out there, with tonnes of info.

Madreal's stuff are always fun and distinctly unique, he's also Canadian. A talented artist.
