This is the friendship network of the online social site Friendster. Nodes represent users and a directed edge indicates that the user on the left side has added the user on the right side to his friendship lists. The network is directed as adding a user to ones friendship list does not imply that the added user has marked the other user as a friend, too. As some of the friendships lists are private some information is missing in the network.
