Introduction

Abstract

Social Network Sites (SNSs) such as Facebook have been gaining momentum and attracting a large number of users. Boyd and Ellison (2007, p. 211) define them as “web–based services that allow individuals to (1) construct a public or semi–public profile within a bounded system, (2) articulate a list of other users with whom they share a connection [regularly referred to as SNS–friends], and (3) view and traverse their list of connections and those made by others within the system”.
