I recommend checking out some of the examples provided by Firebase. In particular, something like angularFire-seed (https://github.com/firebase/angularFire-seed) is a great way to get started. Firebase can handle user authentication and data storage. AngularJS + Firebase is an amazingly productive combo. Set up Bower and use Bootstrap for the user interface, you’re all set.
It would be a great idea to set up some boilerplates for StaticApps.org showing how easy it is to get started.
