Browser Applications Framework That is based on Rails, CoffeeScript and love

I could definitely get behind this. My issue with Ember and Backbone is how alone I feel when I'm trying to write something. Honestly, the convention of Rails has always been really, really nice (until you hit a breaking point, but by then you usually know what to do in some other way). I like the opinions and I like that they are trying to make it drop dead simple to get up and running with minimal fuss.
