There’s an interesting post on warpspire.com at the moment, decrying the speed of implementation for HTML 5 and CSS 3 and suggesting Flash/AIR as a better alternative. I completely disagree with it, but it’s interesting nonetheless. HTML 5 in particular comes in for heavy criticism as it’s perceived that its adoption will take too long.
But, as the title of this post makes clear: you can start using HTML 5 right now!
Well, you can’t really — but with Opera and Safari, you can at least pretend to while you get used to the syntax.
