Tim Bray on Web Services Theory and Practice:

"I think somebody needs to stand up and start waving a flag that's labeled 'WS-Simplification' or 'Real Web Services' or something, that's all about building applications with what's here today and what works today: XML, HTTP, URIs, SOAP, WSDL, and that's about it.

People who need solutions today are building successfully today with that toolkit and I know because I've seen them. Save the future for the future and don't bet on research projects, leaky abstractions, or the inventiveness of committees."
