REST has nothing to do with JSON. How dare you saying that no-one uses while you're using the world wide web every single day?
* Until recently, used stateful numbers for all links * Uses the same location for different resources (e.g. https://news.ycombinator.com/item) * Serves the same resources at multiple different locations, rather than redirecting you to a canonical location. * Does posting, editing and deleting via POST, not CREATE/PATCH/DELETE * Does approximately no content negotiation * Does not support non-browser clients at all, which, well I suppose you could make a perverse argument that that is HATEOAS.
In short, it behaves not at all like the system described in the REST paper.
