Building a REST API architecture in MVC 3

Very nice article, more than enough to get up and running with REST under ASP MVC3.
It feels a lot like the Nancy project https://github.com/thecodejunkie/Nancy but with the benefits of having MVC baked in should you need it.

I have implemented a similar restful architecture for comments in my blogging application: http://liteblog.codeplex.com.

One thing that I like to point out is you have not covered how to use these JSON objects from Javascript. This will make the post a very good reference material.
