Citizen 3.0 discusses three images of government - as networks, parties, and organisms - and how the roles of citizens may change accordingly. It poses several research questions about optimizing social networks, designing government services for egoistic online citizens, and developing "vaccines" against bureaucracy and an "epidemiology" of power and information. The document emphasizes that social orders and concepts of citizenship are evolving due to technological and information changes, and calls for developing long-term perspectives on e-government.
