Smiler i have no idea what your talking about, as far as web 2.0 it just basically referred to gradients, shine effects, table-less coding and of course xhtml and css standards. There's no major difference between web2 and traditional web-design.
For fair reference web 2.0 has developed even further then it's original meaning, now we have html5 which has opened a number of doors not mention browsers finally are coming closer to css3 and html5 standard.
I disagree,
Web 2.0 was a predictable concept. It is more like a transformation from a traditional, old-school plain html page, to a web
application, something with real functionality as opposed to static information. Many static old websites could not introduce the general public into having an input online, social media is a good example of web 2.0.
We see more and more ajax powered websites which i believe is really the essence of web 2.0, industry-leading websites are now leading with web applications as opposed to a traditional website. Load the page once, and the rest is done via javascript. The general public doesn't notice what's happening, it might as well be a traditional program running on their screen.
html5 and css3 are new coding standards with new features and functions, NOT concepts. They bring more flexibility and new options, but are not necessarily a development within web 2.0 that has exceeded web 2.0's predicted functionality and goals.
Wikipedia gives a decent explanation:
