Okay, I'm late on this, but here's my list..
Sinfest, Sluggy, and Kevin and Kell (of course)
User Friendly (Can tend to be a bit heavy on the geekiness, but often amusing)
Sexy Losers and
Everything Jake are both updated on a less than daily basis, but I enjoy both. Sexy Losers is very explicit sexually, and very sick and wrong... and I love it. Everything Jake used to be a comedic daily, but it's turned into a serial superhero thang. Nice drawings, but he desperately needs an editor.
Pibgorn, Pearls Before Swine, and Get Fuzzy. They're actually on
Comics.com, but I can't find them in any newspapers. Pibgorn is a serial comic about a fairy, a demon, and a church organist (really!). Pearls Before Swine is just.. weird, but funny. By an odd coincidence, my husband and I found out that we're two degrees away from the cartoonist. Turns out that he's a pretty nice guy. Get Fuzzy is pretty popular, I think. It is about a stupid, mean cat; a stupid, nice dog; a smart ferret; and an guy in advertising.
