David Weinberger’s keynote from the FastForward08 conference:

“…As information – and, importantly, metadata – get digitized, we have to unlearn millennia of lessons reality has taught us. The changes affect not only the basic principles of organization, but also who gets believed and why. In this session, David Weinberger explores what happens to experts, authorities, and the business and institutions that depend on them as we move to social knowledge, rich in connections but often uncontrolled and uncontrollable.”
