I think Roy Fielding and the other strict REST proponents need to do a better job of explaining why we laymen should follow the rules so closely. I have read a lot of Roy's work, and those of other proponents', and I still don't see a lot of value in staying so strictly to the 'word' of REST.
Much could be helped by 'the experts' just showing us rational laymen the cost-benefit analysis. Show me how things will fall apart over time, some data would be helpful. And let me see some case studies.
Currently, my non-REST "REST" interfaces seem to be working pretty well. And, when they don't work, I go and fix them. Seems easy enough, but obviously I'm naive.
