SOAP and UDDI taking time

Another good tip from SOA today pointing to stories questining the uptake of SOAP and the necessity of UDDI. This is one of the key problems of large-scale interoperability - you only value what everybody else uses - the less cases there are of people interconnecting between their own services and those deployed by others they less important the standards are. Interestingly work in the Semantic Web Services (e.g. WSMO / SWSI) community is pushing in exactly the opposite direction - more structure not less - is this wise? Or better - how can people be persuaded to use it, probably the only answer is when there are tools available that are as simple as the simplest alternative.
