XHTML, XForms and Device Independence a presentation by the W3C’s Steven Pemberton. The quote about Google forcing usability was noted on Boing Boing, but there’s plenty more about structural HTML, why XHTML is a good idea and how some common practices make the web harder to use. The source code is worth looking at, as an example of how clean HTML should probably look. I just wish he would have used ids or named anchors to make it easier to link to specific items on the page.
