My favorites are definitely Hyperbole and a Half and The Daily Dalek. I usually look for stuff that makes me chuckle. I also think Comic Who is cute most of the time, and I have a friend in S.A. who is a cartoonist...he is absolutely brilliant but he shut down his website, which is a bummer. He often shared comics about his experiences with kidney failure and parenthood. Maybe some of his stuff is still online somewhere. It was called Yummy Lemons.
