my only question regarding RESTful api's is... is it really that hard to implement? I know there's a few set of rules/principles to follow but in the end, I just see "lets make a readable and easy-to-understand API that has a nice set of plural "subjects" with the basic HTTP request verbs all nicely applied. I ask this because I noticed while applying for jobs, that some people hiring simply want someone who can write a REST API but I just didn't see it as a big deal when you're hiring a web developer as long as he has the experience and good mentality for creating organized code.
