Feedbook - an alternative to textbooks

from Dave Cormier comes the notion of the Feedbook

"The feedbook is a collection of feeds (including podcast, blogs and someday soon hopefully vlogs) contained in an open ended opml first seeded by a course instructor and added to (or pared down) according to student needs.

This would make up the main 'textbook' for the course. The students would not be getting a textbook positioned from a single instructor from last year or even a couple of years ago, but a collection of essays written right now about changes that affect the current issues in education. The instrutors can add their own flavour to the course in their own blogs as well as modeling blogging as good educational practice."
