I feel the same way. My first API on my current project was a horrible mess, and did I only realize why it sucked and what I needed to change when I decided to play with Backbone.js over a weekend using my API as a data source. The only way, I think, one can build a RESTful API is to do it from the client's perspective, much like BDD builds software using a list of actions the user wants to make. If you're not using your own API, then it's probably broken.
