Knowing Your World through Social Media

This panel discusses how social media may shape users' knowledge, worldview, and even relationships. These media can make us feel like we know a lot about other people, events, and issues. But how much do we really know? How accurate is information spread through social media? Who is trying to persuade us using social media? And what does it mean to be a "friend" or "follower" online? The panelists, four experts who represent politics, journalism, public relations, and psychology, explore these questions in a wide-ranging discussion.
