Social Networks
Facebook allows users to search for users of Facebook, and to add them as their friends. When adding a
friend, Facebook allow the user to add details about the relationship. For instance, a user can add details
that the two people have gone to summer camp together, or have traveled together. There are also other
networks besides the friends network. Users often join the network of their school based on graduation
year, or the network of their workplace.
