Haven't tried it, but I heard great things about it from bradfitz, who uses it on http://camlistore.org/ (and whose opinion definitely deserves respect). Is React an all-or-nothing thing, or can you sprinkle it in certain places on your site without needing to make the whole site in React?

The great thing about it is that you can sprinkle it in just where you need to have some dom manipulation.

TBH, a lot of sites really overdo the client-side rendering thing.

We're replacing one Backbone view at a time as soon as they need to get more dynamic. So far I'm impressed.
