Although I see some interesting points about the evolution of the web, I'm not buying the "with web 2.0" distinction. It's simply incremental changes in the way things are done. There is no "web 2.0".

So what exactly is the difference between \architecture of participation\ and this new concept of architecture of partition???

This essay re-examines web 2.0 by looking at its technology stack and impact on enterprise computing, in contrast to the common consumer-centric point of view. Categorizing the landscape into Consumer Web 2.0 and Enterprise Web 2.0, the essay establishes a web 2.0 technology stack that forms the foundation of a paradigm shift called ?architecture of partition?. In the end, the business impact of web 2.0 technologies on enterprises is presented.
