That's dramatic. Learning any new topic, particularly one as involved as REST, require some investment of time. Your blog post has FAR more content than my slides do. And your approach is from a "best practices" point-of-view. So the arc of our stories is necessarily different. I'm glad that blogs enable people to learn the same topic in multiple ways. It's a good for everyone. I just wish people would avoid self-promotion on top of other people's backs. =)
