Dustin's got a flare for minimalist design: he's good at making things simultaneously simple enough that you can grasp them and loud enough that they stand out. Sometimes I come close to admiring him, but he's so smug for so little reason that I can't appreciate him for his talents. Tim van Damme did the superhero thing first and with a tenth the ego; his http://timvandamme.com/ is better-made than anything Dustin's ever touched, spread further than anything Dustin's ever designed, and he never let it go to his head. He's also capable of designing a web site with more than five elements on it at once.
Simple is nice; elegant is better. Dustin seemingly doesn't aspire to elegance and he's content with simply being popular. I don't begrudge wanting popularity, it was hard for me to stop lusting after, but I do begrudge conflating "people like my style" with "I am a great person who makes great things". I love cocky artists, can't get enough of the Dadaists and Philippe Gaulier and jackass Zen tutors who smack you for saying stupid things; but it's got to be earned.
Dustin recently wrote a post that made the rounds which I admired because he seemed to be saying, "I'm not satisfied with how good I am; I want to be better, and do something worthwhile." He strikes me as a guy trying to do the right thing and going about it the wrong way, and I sympathize with him a whole lot. But his ego is hilarious and way out of proportion with the rest of his work, and I find it endlessly amusing how bad he is at handling criticism, endlessly irritating how certain he is that he doesn't deserve it.
