One of the things I like to do when I'm NOT writing is to read webcomics. Right now, I've got three that I check several times a week, and that are long-running and frequently updated:
Something Positive - So much anger. So little time.
Clan of the Cats - Urban fantasy, great art, interesting storylines
Templar Arizona - weird alternate-reality thing. I haven't figured it out yet. but I likes it.
Zombie Hunters - Zombies. Blood. Gore. Humor. What's not to like? It has been running a little slow the last couple of weeks (could we advance the storyline? Please?) but I still like it.
