Robert, do you have a reference for his suggestion?
Point of Information to our younger readership: Scott McCloud is a talented cartoonist and blogger on Cartooning; but is best known for two "deep-think' books: Understanding Comics, Volume 1 & 2; published in 1993. They're fascinating thoughts delivered in a graphic-novel format. Really, really worth checking out of your public library. He published further books in 2000 and 2006, which I have yet to read.
