This document discusses Enterprise 2.0, which refers to using emerging social software platforms within companies or between companies and partners/customers. It defines key attributes of Enterprise 2.0 like being platform-based, social, and complementary to existing organizational and technical structures. Examples are given of companies using social platforms internally like Intrawest's use of blogs and tags. Challenges to adoption within companies are also discussed, such as imposing too much structure versus allowing emergent platforms to form organically.
