This document discusses the shift from traditional business hierarchies and models to new social architectures enabled by networked technologies. It argues that successful 21st century leaders will transform their leadership approach and organizational structures. The principles of social architecture that will be covered include moving from audiences to communities, hierarchies to networks, control to empowerment, consumers to creators, and targets to orbits. Real world examples will be used to apply these concepts. The overall goal is to gain insight into social leadership in a networked world.
