John Seely Brown is a remarkable thinker. His book The Social Life of Information and his article "Growing Up DIgital" are the result of deep and patient thought about society, education, human nature. This is his homepage that brings together in one place his work, his ideas. Highly recommended reading: 'Growing Up Digital."
An amazing collection of info related to archetypes. I think it was originally created for gamers but it is a fascinating wiki a student of mine turned me on to.
