Just to amplify: there's more than a pedantic difference beteen the two. REST has a lot of serious advantages related not only to application architecture and interoperability but also to system architecture and scalability. There's a lot in the original REST dissertation about removing shared state and enabling cacheability. The crowd that mistakes ROA for REST (I think) sees the stuff in REST that relates directly to development and gets excited - but the stuff related to making their app scale, they ignore. If you don't want to learn a little bit about everything, at least follow the rules that relate to the things you don't know about.
