When Manuel Castells wrote his book on the Internet Galaxy in 2001 we could already see that knowledge and learning would become a major asset of future societies and economies, and that disruptive digital technologies were going to enable this societal transformation. But we did not have a clear view by then on how technologies would revolutionize the way we process information, share knowledge and learn. We still considered learning as a mental process of the individual trying to internalize information. Now, in 2010, we can see that learning is enhanced by technology as it evolves into a shared process of communities trying to externalize information and co-create new knowledge, which is quite the opposite of the pre-digital era.
