Y'know what's kind of cool? Cyanide and Happiness.
One of my all-time favorite webcomics, as well as where we got the idea for sharing cool stuff (although they mostly do it for other webcomics). Anyway, thanks to their low-quality drawing and multiple authors, they get to update daily, and have a library of about 2500 comics so far.
A clever blend of childishness and dark humor (not to mention Depressing Comic Week) keep this webcomic entertaining. Visit it at explosm.net.
