Bill Mudron is a great comic book artist and painter. So why can't I find a working website of his stuff?
A dream of mine is to open a website, connected to a physical gallery somewhere, that sells visual art in the couple-hundred-dollars range. (Prints make more sense than paintings at this price, unless the painters/illustrators live in third world countries like Georgia, in which case $250 is a fortune.) These operations already exist, most of the art is so bad that no one uses them.
See for example Etsy, a beautiful site with cool flash toys to search through the art, which is too bad because the art sucks.
