Um.
Girl Genius
(you can now read the whole of issue one at that link)
Gold Digger (official fansite)
Knights of the Dinner Table
(the online strips)
Um. I think that's it, at least as far as the 32-page staple-bound pamphlet form goes. Astro City when it appears. A couple more things, once they get collected:
Invincible
(damned if I can find an official web-page for it)
Mostly, though, I'm reading webcomics and manga.
