Ryan North is a really nice guy. He came to give a talk at my school and it was a lot of fun to watch.
I remember him saying that after a few months he was getting concerned with the restrictive format of Dinosaur Comics until he realized something -- he can have speech lines going OFF OF THE PANEL to have other characters be in it.
I'm glad he realized that since God is such a good character.
