Web 2.0 – This is about user-generated content and the read-write web. People are consuming as well as contributing information through blogs or sites like Flickr, YouTube, Digg, etc. The line dividing a consumer and content publisher is increasingly getting blurred in the Web 2.0 era.
Web 3.0 – This will be about semantic web (or the meaning of data), personalization (e.g. iGoogle), intelligent search and behavioral advertising among other things.
If that sounds confusing, check out some of these excellent presentations that help you understand Web 3.0 in simple English. Each takes a different approach to explain Web 3.0 and the last presentation uses an example of a "postage stamp" to explain the "semantic web".

What is the Semantic Web?
The Semantic Web is a web that is able to describe things in a way that computers can understand.- The Beatles was a popular band from Liverpool.
- John Lennon was a member of the Beatles.
- "Hey Jude" was recorded by the Beatles.
Sentences like the ones above can be understood by people. But how can they be understood by computers?
Statements are built with syntax rules. The syntax of a language defines the rules for building the language statements. But how can syntax become semantic?
This is what the Semantic Web is all about. Describing things in a way that computers applications can understand it.
The Semantic Web is not about links between web pages.
The Semantic Web describes the relationships between things (like A is a part of B and Y is a member of Z) and the properties of things (like size, weight, age, and price)
