  As my point of departure, I would use social activities that people engage in in real life, assuming that some day, some smart entrepreneur will figure out how to migrate each activity to the web. So, for example, what are social activities that people engage in, in real life? A few examples: sharing photos and videos gaming sharing restaurant recommendations sharing doctor referrals sharing product recommendations sharing music recommendations sharing movie recommendations sharing book recommendations sharing magazine/newspaper article recommendations sharing job recommendations sharing travel recommendations sharing personal news providing dating referrals providing introductions asking questions sharing investment recommendations sharing lawyer referrals selling homes selling goods selling services In addition to the traditionally social, offline activities, I am sure that there will arise activities which, were not social in the offline world, but due to the unique characteristics of the online world, become social. Thanks!
