COMICS WE LIKE (which therefore makes them of only the HIGHEST quality)

XKCD - A webcomic of romance, sarcasm, math, and language. Don't let that put you off though, or the really tedious layout.
Platinum Grit - Alright/slightly nonsensical plot, better-than-average character writing, and supreme artwork. Beautiful but confusing.
Cyanide and Happiness -
The Perry Bible Fellowship - Inimitable, though many have tried, including myself.
Dinosaur Comics - If you can be bothered with all the reading, you'll find this is the most consistently funny daily webcomic out there.
Combustible Orange - A charmingly angry comic about comics. Start from the beginning for God's sake.
Chainsawsuit - Hit and miss, but updated so often that checking back at least once a week will definitely be worth it.
