A talk by Dhananjay Nene targeted towards "Why REST".

Here's the brief summary :

The talk will attempt to provide a background for REST and its applicability in today's application interface definition and inter application integration. It will also aim to provide the audience the conceptual understanding required to model application interfaces using REST. The talk will not focus on language or code or tools, but shall restrict itself primarily to discussing REST and its usage at a HTTP transport level.

The target audience is not programmers who will write code to meet defined restful designs. It is the designers and architects who need to focus on how such a restful design should be structured.
