Jon Udell - Tantalizing hints of the Knowledge Navigator:

"It's all compelling stuff, but there's something about Avi Bryant's [Dabble DB] maneuver that shouts Knowledge Navigator. In this 90-second excerpt from the screencast, you can see how Avi hoists data right out of a web page and weaves it into a structured view. So natural, so powerful. How can we not have this capability always and everywhere?"
