Restlet Studio (http://studio.restlet.com/) let's you visually craft your REST API and then view it as Swagger 2.0 or RAML 0.8 source code by simply switching tabs.
It is entirely free and available as a simple web app and installable as a Chrome app. Disclaimer: I work at Restlet.
I fully agree. Fielding warns in his dissertation about design by buzzwords himself.
Almost all web APIs out there aren't REST APIs because they don't respect the "driven by hypermedia" constraint which makes sense because this constraint was put in place for human users driving applications through web browsers, not for machines.
