Actually, "Megatokyo" is an online comic, which has already three actual books out, with a fourth on it's way.
Minitokyo is that art and anime fansite, like Neon said.
I'm really eager to get the fourth volume, all of the characters have evolved so much since the third volume and I've grown to like Erika, Largo, Piro and Kimiko even more then before.
