Thing is, you can kind of feel sorry for Dobson... kind of.
Diaz is a whole 'nother level of shit, though. His comic doesn't look the worst, but it has no internal consistency because he jerks off too long between pages, and by he time he gets around to making a new page, he's already forgotten what he did on the last one. He keeps dropping hints Marvel or Disney should let him do covers or something, but he has no ability to stick to a deadline the way real professionals do.
You know, I can tell you, I've been in the webcomic game for eight or nine years now, and I can say from personal experience that most comickers will sort of band together to help each other out. But not once (not once!) have I ever heard anything good about Diaz. I've never heard of anyone saying, "Gee, Arron gave me some good advice about such and such," or, "I was at a convention and went to a panel Arron was on and he really inspired me to stretch as an artist," or "Man, Aaron gave me a great tip on how to draw this, that, or the other," or, "Wow, met Aaron Diaz, and he was so cool! Really friendly, nice guy, approachable, etc." All I have ever heard about him is ego, ego, ego. The guy you never want to play board games with because he'll argue every little rule when it goes against him, but argue the opposite when the rule goes against other players. I've heard him described as arrogant, egotist, condescending, self-important, even rude.
But never anything good.
