This document discusses the use of social media in government, or "Government 2.0". It proposes a model for how governments can utilize social media at different stages: information socialization, mass collaboration, and social transaction. It also outlines three scenarios for implementing Government 2.0: standalone, nested within existing e-government systems, and a hybrid model. The document concludes that while social media is currently used mostly for information dissemination, it has great potential for developing countries to foster more collaboration, transactions, and citizen participation.
