I was playing around with Yahoo Pipes on the weekend. Some have called it "a milestone in the history of the internet"...others aren't too impressed. I fit into the "I'm impressed" camp. Not for the technology itself, but how it relates to what I've been saying about learning and technology for the last few years: the networks we create are our structures of learning. Pipes allows individuals to filter data in a manner that is personally relevant - i.e. data from many sources meets the needs of the end user. Simply, open data repurposed and re-created for personalized needs.
Jon Udell: "The dominant way in which most people will “program” the web is by writing metadata, not code, and we’ll need an interface as friendly and powerful as Pipes to help them do that."
