Penny Arcade
This is one of my favorite on-line comics, and one of the few entertainment sites that I check regularly. While it focuses the cartoon misadventures of two archetypical computer/videogame geeks, it does provide the ocasional pearl of ingenious insight.
Tycho’s writing is engaging and provocative, and Gabe’s drawings are always fresh and cartoony. Go ahead and check it out, and maybe you’ll catch them in a good day and become a regular as well. Cheers!
