The bottom line is that the old model of the central webmaster hand-spinning every page of every website and, worse, manually adding the navigation necessary to help users find it, just isn’t scalable or viable. The only feasible course for the future is for content to be posted by the content contributor, whether that’s the site owner or site visitors, and for the best possible navigation to be constructed around that content on the fly.
In other words Web 2.0 isn’t an empty slogan
