A little outdated, but some webcomics I read include:
Misfile, a story of a guy who was turned into a girl, a girl who became 2 years younger than she really is, and the pot-smoking angel who did this to them.
Order of the Stick, a story of D&D characters traveling to save the world... one crack in the 4th wall at a time...
Looking for Group, kinda hard to explain, but it's about an elf who meets a warlock, and it goes on from there.
Cyinyde and Happiness, The "Dainel Tosh/South Park" of webcomics.
Prequel, Tom reads this. I assume it takes place in the same world as Skyrim.
The Pits Comic (no longer on the internet), "AKA: NASCAR Abriged". It made fun of several incidents in NASCAR over the past couple of years before being brought down off of the web early last year.
That's all I can think of for now.
