I read a couple of comics! Here's the links:

SMBC (Updated every day. Quite random)

Goblins (Very fun adventure about a group of goblins in a DnD world who take up classes and go adventuring)

Gunnerkrigg Court (A school girl attends a special school where everyone seems to have some kind of power, and really weird (and funny) things seem to happen)

Locus (NSFW!! A wicked tale by Adam Black about a half-succubus woman with a bad-ass sword and a monstrous uncle)

Silk and Honey (Also NSFW! A prequel to Locus that takes place as a Western with monsters and magic)
