Scotch on the Rocks 2010, Day 1 part 2
A whistlestop tour of HTML5 and CSS3
Chris Mills (Opera)
I should have bumped into the speaker before now really, as he's from Manchester, but we'd never managed it :-)
Anyway, Chris started with a bit of history, namely that HTML4 is not dead. It can't do some things like video, which is why Flash got started in the first place. One great quote was 'bullshit will HTML5 kill Flash'.
