I wouldn't really know. I generally laugh when I see articles talking about web 2.0 and by the time they talk about web 3.0 I'm wiping tears from my eyes. I think web 2.0 is websites with the letter "r" on the end of the name.

I could post a ppt:-)

The consensus generally seems to be that web 3.0 is 3D / virtual world web 2.0.

In MIT I am told web 2.0 is SOOO last Tuesday.
