I now get you, Dave… or rather the MOOC textbook idea. A MOOC as a regular on recurring community that revisits, revises the content it produces in a subject area.
Doesn’t some of this hinge on a new concept of what a textbook is? Moving away from the monolithic finished product to something that is dynamic, on-ongoing?
You got me thinking (as usual). There are a ton of fragile points, but that’s no reason to not pursue.
