The document discusses the differences between designing social software versus non-social software. It notes that the primary goal of social software is to convince someone of something, rather than just getting a task done like with non-social software. The document advocates that social software must be studied in the context of actual user behavior and social implications, rather than just focusing on the interaction design. It also discusses several social theories that could help guide social design, such as theory of mind, cognitive limits on group sizes, and how people present themselves differently depending on context.
