You mean using JavaScript to write HTML5? I sure don't want to develop anything with a UI using nothing but JS. I must be misunderstanding you.

I know HTML5 is not all the way through the standards process yet. But it is already being used in 30-something of the busiest web sites.

>In your other thread, you noted the difference between a standard (sort of) and a development ide. There's more to it than that. Think of everything that goes into making a UI do what you want. And what will you be doing it with? JavaScript. JavaScript, according to the guy who wrote it (Brendan Eich), is a mess. And according to perhaps the most-recognized guru on JavaScript (Douglas Crockford), it took him 10 years to figure it out. Some development environment.
