Mark Baker: Yet another service which opts for REST rather than SOA. Victory is mine! Muhahaha! 8-)

You know what distinguishes this "definition" of REST from WS-*? A blank line.
But I suspect it will be popular anyway. Del.icio.us certainly is. And it is even further away from REST. Here's code that will do a posts/add request using HTTP GET. Sweet.
You know what people like in APIs? Hint: it is not where you put the blank line. People like it when you don't need to throw in the kitchen sink to make this work.
