Query: De-Virtualizing Social Events: Understanding the Gap between Online and
  Offline Participation for Event Invitations   One growing use of computer-based communication media is for gathering people
to initiate or sustain social events. Although the use of computer-mediated
communication and social network sites such as Facebook for event promotion is
becoming popular, online participation in an event does not always translate to
offline attendance. In this paper, we report on an interview study of 31
participants that examines how people handle online event invitations and what
influences their online and offline participation. The results show that
people's event participation is shaped by their social perceptions of the
event's nature (e.g., public or private), their relationships to others (e.g.,
the strength of their connections to other invitees), and the medium used to
communicate event information (e.g., targeted invitation via email or spam
communication via Facebook event page). By exploring how people decide whether
to participate online or offline, the results illuminate the sophisticated
nature of the mechanisms that affect participation and have design implications
that can bridge virtual and real attendance.
