Sluggy has considerable development. It's just that Pete does something which annoys the hell out of me (though not *QUITE* enough to stop) by doing Really Light storylines that depend on the characters reassuming familiar roles (this is, at least in Torg's case, becoming more and more obviously a defense mechanism or a deliberate act, not a matter of him failing to develop). Then he drags me back in with Serious Storylines of Awesome like he's doing now.

Currently I'm following Sluggy, Girl Genius, Sinfest, Something*Positive, Schlock Mercenary, and The Dreamland Chronicles.
