what's deal with Web 2.0

Paul Graham talked about Web 2.0. And the main point is, using the web the way it's meant to be used. I think the most important is providing the tools and freedom for users to create their meaning.

Mathew Ingram gave some words about Web 2.0 and the idea related of "the Web as a platform". Irrespective of Web as a platform or something "you should use to build a platform", the point here is the interaction created by users and the meaning behind that interaction.

Paul Graham provided three components of Web 2.0: Ajax, Democracy, and Don't Maltreat Users. I won't give so much weight to Ajax. It's just a method to provide the opportunity to the meaningful interaction between users. Don't Maltreat Users is not a very accurate term, even though I know what he was meaning. It's better to call the component "Don't offer unmeaning stuffs to users". Flickr requires users to register but that doesn't matter because that's meaningful. A site providing free stuffs and extremely Ajax interface but unmeaning to its users still fails.
