"What's the difference between a comic book writer and a pizza?" "A pizza feeds a family of four." - Bah-boom! I apologize if I'm misquoting this joke by Mark Evanier but I think I've got it mainly right.
I believe that people who create -- who make things (comics, music, whatever) -- have value and should be valued but I have no illusions that life is always fair. I'm very skeptical about the likelihood of my being able to make a significant living from web cartooning so, no, I don't expect to entirely support my family on web cartooning. I am simply curious -- and very motivated -- to see what is possible and to try to find a way to make web cartooning as viable as possible for me. And I'm willing to share my mistakes and stumbles and general discoveries along the way because I think it's interesting and I think that others might find it interesting too. As always conversation on this topic (or any topic related to web comics) is welcome.
