The Drawing Board - great art critique and commenting forum for talented artists. High level of talent so i only read it :)
PvP - Done by the one and only Scott Kurtz, that guy's a machine, he may be late with some of his strips, but he still gets them done daily (having done that myself for 2 years i can say its no easy feat)
Penny Arcade - Hilarious comic done by Gabe and Tycho 3 times a week, i recommend it.

Anywhere but here - A great comic by Jason Siebels telling the story of an unnamed guy forced to go to college in North Dakotah, the most bland place in the Universe. The art style reminds me of the funnies section of my local newspaper. Very cool and a must read.
