Get to know Emily Lewis, who will be on a panel at SXSW Interactive this year. This is a recent talk she gave to a local tech group called Webuquerque. She talks about the basics of good markup, semantics, and new concepts in markup. It’s about an hour long.
I think it would make a good resource or assignment for web education students.
A text summary and the slide deck are available on the Webuquerque site.
Other speakers and talks from Webuquerque meetings are available on Vimeo.
