Mark Lucovsky, one of the people responsible for .NET at Microsoft, says "SOAP 1.0 is very basic, there's a need for advanced capabilities..." The reason he says this is that he isn't very creative. Neither are the people working for him. It's been said before, the real need is for better ideas, not "better" tools (although better tools might contribute to realizing a good idea;-)
Google is a web service that has a viable business model. They don't need SOAP, .NET or UDDI to deliver. At Google they are very creative about search and about ways to earn money without affecting the user experience negatively.
