YouTube has had HTML5 video for a while. I actually like the HTML5 viewer more than their flash one. You can start using it at http://www.youtube.com/html5.
The one thing they don't have are ads for the HTML5 videos, so things like music still have to be viewed with flash.
Two Things:
1) I'm surprised by how low C# is. Actually, maybe this is more of a not-advertised-on-twitter thing rather than the popularity of the language, which makes the difference interesting.
2) Die flash Die!
