I read: author wanted to make his website pretty, but IE was making it hard, especially since he was developing on a Mac which made it harder to test, so author dropped support for IE. Author then explains less than 10% of his users use IE, anyway, so it doesn't really matter. Sparks browser war.
While I admit, IE really blows, and I hate developing for it, it's really not that bad. It's manageable if you test on it often, which author failed to do. Is it hard to make a 9 cell table to get rounded corners? Or how about learning "hasLayout" which fixes virtually every IE6+ css rendering bug?
