What are the best practices for RESTful API Design?

My answer to the question can be found the recently released RESTful API Design Book. It is packed with best practices on many technical aspects of RESTful API Design, such as the correct use of resources, URIs, representations, content types, data formats, parameters, HTTP status codes and HTTP methods.
