A lot done more to do
Web 0 infinite eyeballs
Web 1.o Transactions
Web 2.0 Participation
Data INTEGRATION hasn't changed much really; cleverer techniques but bascially a brute-force approach

UGLY
Web 3.0 (aka Semantic Web) is coming as the marketplace expects and demands it: question is whether it is more of the same market-hyped activity or a truly innovative game-changing phenomenon!

IT'S A DATA PROBLEM

Smart linked data is created by putting structure on text where there is none. There are three main approaches: Folksonomic, Taxonomic, and Ontological
Folksonomic classifications: Created by users using tags to annotate and categorize content.If enough people tag content, the wisdom of the crowd identifies concepts. It gives a statistically inferred relationship!

Relationships are created which can then be linked across web pages. Folksonomies are relationship light
Taxonomic classifications: Experts describe a thing or concept in a hierarchical tree with parent/child relationships. Hard to merge concepts through trees!
Ontological classifications: Are taxonomies with rules and are graph basedLots of possible relationships not just parent/childConcepts can be more easily joined with graphs
