Clay Shirky has an interesting take on the point behind the Semantic Web:
The Semantic Web specifies ways of exposing these kinds of assertions on the Web, so that third parties can combine them to discover things that are true but not specified directly. This is the promise of the Semantic Web -- it will improve all the areas of your life where you currently use syllogisms.Shirky's essay is possibly the biggest and most thorough condemnation of the semantic web that I've ever read. (That statement in and of itself says quite a lot.)Which is to say, almost nowhere.
