Seems like this page could definitely benefit from some sort of Hello World. What are the primary components, and how do I run it? Perhaps it's not meant to be a simple library, so I'm not trying to say dumb it down. But is there a more digestible way to understand hr.js without having to read the full documentation?

I'd love to see comparisons (as said in another comment). I like the idea of a grown-up Backbone. I'd like to see if there are any smart view rendering optimizations (like Ember has).
