From you're massively oversimplified statement I can only conclude you don't understand REST. HTTP != REST. REST is how the architects of HTTP generally expected things to work, but due to tunneling, and other approaches to API design it, generally speaking, most systems that operate over HTTP don't actually work that way.
In fact I'd be willing to bet this comment form isn't all that RESTful.
if you used a browser to write that comment, I would say rest is working pretty well.
