I am a "Web Me Too, Oh..." guy.
Yes, I failed to fill out the proper paperwork and declare myself an official Web 2.0 guy prior to the November 2005 deadline. Now I must wear that humiliating "me too" badge.
I've been told that I'm not allowed to skip directly to Web 3.0 due to some amendment that Tim O'Reilly put into law. Apparently, Web 3.0 will be released but only at a secret conference of uber geeks that write mean things about Microsoft and donate to EFF.
In the meantime - I too am attending SPARK. Let's get real... we've got a major shift going on in the presentation layer, collaboration, content management/distribution and self-service programming. The discussion has shifted from REST, WS-*, etc to client consumption models, combining multiple services, utilizing markdown languages and light weight scripting languages.
It is very clear to me that the Web 2.0 movement will drive the demand for SOA. Perhaps more importantly, Web 2.0 will mandate the technical requirements for SOA. The Web 2.0 manifesto is the requirements document for SOA 2.0.
