By all means, you're perfectly welcome to be a purist - I just don't see that as a justification for writing off all online comics as "sucking big time" just because they don't appeal to you. :)
I figure I might as well contribute my own favorite comics, since I took the time to sign up and everything...

Monty (formerly Robotman)
Pearls Before Swine

As far as I know Penny Arcade is penciled, then Gabe uses Photoshop to ink and color. And if I'm not mistaken, Something Positive is colored through computer.
There are very, very few online comics that make no use of a computer in producing the comic.
I'm gonna have to jump in here - actually, a whole lot of the comics currently online are completely produced by a computer. Comics like 8-Bit Theater and Diesel Sweeties are obviously digital creations, with no real similarities with paper and ink comics.
But does that mean they don't...
