My take-away is this: Protocols should always be defined independently of any existing code.

The code-first approach only works well when you're doing something self-contained. Which, an API, almost by definition, is not.

I generally try to design APIs from a consumer perspective, and then usually I end up with something RESTful. Let the server do whatever it has to do, you know?
