Well, that's it, I'm hooked. After spending the last two days reading Girl Genius thanks to
Bruce I was thinking that the cellar has given me links to a few neat webcomics thus far (also thanks to Zip, Beest, and I blame Flint for the robot one, since he's clearly one of them) and I wondered if you guys know of any other good ones. I come across mine using stumbleupon mostly, so it's totally random if I find a new one.
I'll link you to the ones that I currently read, feel free to post the ones you read here too. (I'm linking to the first of each of them, so you can start from the beginning and work your way up.)
