I've been serving this blog as HTML5 for a while now, but that was basically just a change doctype. I've now redesigned, with some layout inspiration from Daring Fireball, and I'm using the new HTML5 structural elements. My goal was to get rid of as much clutter as possible, both visually and in the HTML and CSS, and give myself a more enjoyable base from which to experiment.
If you notice anything broken or ugly, or you have any other feedback, please let me know.
