Like a lot of folks my age (in their 30s), I grew up on comics, both comic strips in the newspaper and comic book magazines. Here are the "geek" comics I follow nowadays on-line:
I used to follow the Heroes Happen Here {Comic Series}, but that one is done. If you're reading this and follow a different one that is a good stress reliever for you, post it in the comics. I'm looking for others. As far as non-geek, I also get Snoopy, Dilbert, and B.C.
