Scandinavia and the World, and Extra Ordinary are some I like. Oh and Hark, a Vagrant.

A lot of people seem to be hyped up over Homestuck... I refuse to read it purely because of the annoying fans lol. Each one I've seen have gone to the obsessive level.

And I know these are not webcomics (though they kind of are), I suggest Hyperbole and a Half, and Books of Adam. They're funny blogs. They both tell exaggerated stories of happenings throughout their lives, but they're hilarious. Each blog has illustrations in them, so they're kind of comic-y.

Edit: Gah, I keep thinking of stuff.

So You're a Cartoonist
Cat vs. Human (cute short comics)
