Social media have accelerated communication, expanded business horizons and connected millions of individuals who otherwise would never have met. But not everything social media touch turns to gold--much of it is brass. Social networking sites are used by scammers, criminals and sexual predators, and many people now self-diagnose illness based on misinformation shared online. Businesses make great claims about social media as a marketing tool but few show any real returns. We communicate through social media but are we really saying anything? Is social media doomed to be a conduit of narcissism or can it become a channel for responsible communication? Can social networking overcome its manifold violations of privacy? Must we sacrifice our identities in order to tweet or "e;friend"e; our associates? This book examines some of the legal and ethical issues surrounding social media, their impact on civil discourse and their role in suicides, murders and criminal enterprise.
