This - Service Oriented Enterprise - is a good blog to read. I'll be following it and hopefully learning things.
I like his summary of his analysis of REST. His point #5 - "Additional exercises should be performed to document how many RPC style verbs would be translated into a more REST-style. Verbs that don't translate shouldn't be forced to fit, rather new verbs should be introduces as part of the first-order vocabulary." - can be an enlightening excersize when you find that a great many verbs actually do translate very easily. And the ones that don't translate easily are enjoyable puzzles and occasionally give me a chance to learn more about the full flexibility and capability of the Web.
