The document discusses the relationship between web content management (WCM) systems and social computing. It argues that while WCM systems and social tools overlap in some scenarios, they are fundamentally different. WCM systems are primarily for publishing and managing websites and digital content, while social tools focus on user-generated content and community engagement. The document also outlines scenarios when a separate social tool may be needed beyond a company's WCM system, such as for branded public communities or internal collaboration.
