Hey,
I just came across this randomly.
http://slides.html5rocks.com/
It's a great resource for HTML5 info including the JS specs and all of that. There's so much gold in it that I flipped out at least three times.
http://slides.html5rocks.com/#web-fonts for example... Not having to worry about web-safe fonts any more? Whaaaat?
Just wanted to share.
Love,
Troy
