This document provides an introduction to social networking and Facebook. It discusses how social networking allows people to see each other as real people and connect in new ways. Social media is fundamentally changing how people relate to one another by providing new opportunities and norms for relationship building. The term "social media" refers to online tools like websites that depend on user contributions and interactions to build shared meaning and value in a participatory, open, conversational, and communal way.
