The document defines Social Technographics, which classifies people based on how they use social technologies. It places people into seven groups - Creators, Critics, Collectors, Joiners, Spectators, Inactives - based on what social media activities they participate in monthly, such as blogging, reviewing, tagging, or just consuming content. Forrester uses consumer surveys to quantify the number of people in each group and help companies understand which strategies may work best for their target customers.
