I saw an article by James Handler espousing the beta of Twine as evidence for uptake of Semantic Web and Web 3.0. While I am excited about growth of the Semantic Web, 20 seconds on Twine was enough to convince me it is not ready for prime time.
I was greeted on the screen with a form asking me to enter what I was into. I entered my three favorite sports team with excitement to see what a semantic smart engine would link me to. The results were not even close. Back to the drawing board.
