Interesting article - your quote "Creating good content on a platform that lets users (teachers & learners) add context may be the the real killer application in education. Content developers and institutions have been so concerned with protecting their content that they don’t see where the real value lies. Letting others add more context will only increase the value of their content."

...it sounds just like what we are trying to achieve with WikiEducator - www.wikieducator.org In creating a vast array of free and open educational resources - at all education levels - educators are experiencing a new way of sharing information and collaborating on projects of interest to them, and connecting to like-minded people all over the word. Moreover, educators are adding value to other educators' content (i.e., handouts, pedagogy, interactive learning activities, collaborative video, etc.) in a way that reduces development time, cost to the organization and increases individual energy and productivity.

Glad to see this type of message coming from you and the blogosphere!
