It's worth noting that this is the personal website of Heydon Pickering, a prolific (and opinionated!) writer and speaker on web design. He's the force behind Inclusive Components [0] and half of Every Layout [1].
Watch his videos. Check out his articles on A List Apart and in Smashing Magazine, among others. Pay attention, he's very thoughtful and you'll probably learn a lot.
