Some web comic links of interest:
RELIABLE COMICS: This is the kind of thing I like to see, David King's latest web comic has a link to a photo of that day's original art. Lots of excellent cartooning.
ANDERTOONS: Mark Anderson has to be one hard-working cartoonist. His art (of which there is a constant stream) is very much in a classic/conventional mode but he has embraced the web in an aggressive (and I hope beneficial to him) way. Worth checking out.
WHAT THINGS DO: Gorgeous web comics by Jordan Crane, John Porcellino and others. No merchandise available as yet so I'm not sure how they're all paying for this. Still, beautiful, beautiful stuff well presented.
