I can see that this approach might be viewed with a lot of suspicion, but this gels with a lot of problems we saw while building the MontageJS framework.

CSS is global, and it is a big problem to manage while building a large web app (which of course Facebook is). I think everyone building a large site or app has come across a bug where a CSS rule is unintentionally overriding another. They are a pain to track down and almost impossible to prevent.

I haven't played with this approach (as it was only talked about today!) but I think it's on the right track. The only thing I would like to see is the "CSS" put into its own module and required into the component JS file. Not only would this maintain the separation of style and markup, but also make it more approachable for those CSS experts coming from the current way of doing things.

I'm really looking forward to seeing how this progresses.
