Browsing the still-in-development HTML5 recommendation is fun.

My favorite addition is the “irrelevant” attribute (which I could wrap around some entire sites I’ve done in the past), but there are all kinds of interesting new gadgets, including a bunch of new dom events, sandboxable iframes, video and audio elements, a “draggable” attribute, a datagrid and more. It’s also worth noting that the “embed” element will now officially be part of the spec, making all kinds of invalid flash embedding suddenly okay.
