Web 2.0 Social Networking Sites

Abstract

This chapter describes one of the Web 2.0 technologies, Social Networking Sites (SNS). A definition of SNS is offered, as is a short history of these sites. The existing research is reviewed and organized to summarize what we know about SNS usage (from the perspectives of student use, general population use and organizational use), and what we know about the antecedents and outcomes of SNS use. The chapter concludes with discussion of new developments, challenges and opportunities. There are many opportunities for future research and organizational applications of SNS as SNS adoption grows at incredible rates.
