According to this:

The great marketing coup that REST folks are trying to pull off is that WS-* is complex and REST is simple. That’s just nonsense – if you really try to build the type of systems that people build with WS-* using REST, then you’d end up just as complex.

Who’s talking nonsense? So, you take something that is inherently complex and build a system with it — then you take something that is fundamentally simple and build a similar system with that — and the final results are the same in terms of complexity?

Mais non. I don’t think so.
