Is The Next Web A Semantic Distinction?

As small groups of Web thinkers sketch out what Web 3.0--the so-called Semantic Web--may look like, how much attention should E-Commerce execs be paying?

In an interesting RetailWire story and discussion, questions are raised about whether this will be a broad transition or merely a niche enhancement for those who bother. But if major e-tailers want to change, the sad reality is that they need to get involved early or surrender the ability to complain later. Given how much E-Commerce execs love to complain, that latter option seems unrealistic. ;-)
