Signals in Social Supernets

  Social network sites (SNSs) provide a new way to organize and navigate an egocentric
  social network. Are they a fad, briefly popular but ultimately useless? Or are they
  the harbingers of a new and more powerful social world, where the ability to maintain
  an immense network¿a social "supernet"¿fundamentally changes the scale of human society?
  This article presents signaling theory as a conceptual framework with which to assess
  the transformative potential of SNSs and to guide their design to make them into more
  effective social tools. It shows how the costs associated with adding friends and
  evaluating profiles affect the reliability of users' self-presentation; examines
  strategies such as information fashion and risk-taking; and shows how these costs
  and strategies affect how the publicly-displayed social network aids the establishment
  of trust, identity, and cooperation¿the essential foundations for an expanded social
  world.
