Chapter 1: Social Computing
T List of friends and colleagues: It can’t be considered a social network if every user is an island
unto themselves. Social networks work to connect users with each other, and maintaining the
list of relationships is an easy way to browse through these social connections.
T Activity or change log: The activity or change log keeps track of everything a user does inside
of the social application and allows the user’s friends to read and react to those changes. For
example, if a Facebook user posts a new profile picture, friends of the Facebook user can make
comments about the new photograph.
T Threaded or unthreaded discussion board: The discussion board allows users to talk back and
forth to each other.
T Subscribe for updates: By using a subscription technology such as email or RSS feeds, the social
application reminds the user to come back and continue to participate in the conversation and
the social experience.
