Google releasing open source code and not revealing if they've ever used it on any of their sites (see 'built with angularjs http://builtwith.angularjs.org/ ) is somewhere between silly and suspicious.
Cool; the page is much improved. This has annoyed me with Closure library in the past, though that's been improved a bit. Users look at it and wonder whether anyone uses it, then Google people insist it's the most deployed javascript framework ever. Which, like, sure, great guys, but why not just say that on the website? Why the intrigue?
I work at Google, but not on the Angular team. Our team has deployed angular.js: places.google.com/manage. Angular's also used extensively in internal projects.
Does anyone know if the public-facing site is supposed to be using Angular? There are no references to the library anywhere in the source of http://www.google.com/doubleclick/.
DoubleClick is a public facing app, but you need an account which you can get only through a sales rep (I believe). The target audience are medium and large advertising agencies and not individuals.
