Twine: The First Mainstream Semantic Web App?

I have heard the Semantic web story since 1998. And I am very, very skeptical. Description logics (e.g. OWL) have been a solution in search of a problem since the 1980's. Really 99% of the effort on the semantic web goes into 'building' vapor-ware. I call BS on these folks and the only way they are going to prove me wrong is by actually doing something that solves a real problem.

In academia the 'group think' among the semantic web folks has been astounding. Try asking them to represent customer-supplier-product type relationships and you will get a vapid or angry stare. Ask them to do anything with time or measure and they start babbling about yet another upcoming and crytic standard. Anything beyond binary relationships gives them major headaches. It takes a database/logic weenie like myself to point this out to them... And I am never satisfied with their answers.
