Today, Hannes and me were talking about html5 at the aptly named Brasserie Lipp for the Internet Briefing TechTalk series. There were quite a few people and it went pretty well (IMHO :)), maybe a little bit too long. Sorry about that and the hungry people.
The slides are available on slides.liip.ch, and if you want more information about html5's spread, there's more in this older blog post about the html5 feature comparison table by me.
