This timely guide examines the influence of social media in private, public, and professional settings, particularly the ethical implications of the cultural changes and trends created by their use.

In the quest for quick dissemination of information, web users and content providers find both opportunity and liability in digital broadcasts. Examples abound: Twitter members tap into news reports well in advance of traditional print media, but stories are prone to inaccuracies and misinformation; Facebook shares useful data mined from member profiles, but this sharing often compromises privacy. It is no surprise that use of social media gives rise to a host of moral dilemmas never before encountered. This book sheds light on the effects of this new medium on the individual and society.

Through two volumes chock full of topics found in news headlines everyday, the authors look at evolving trends in social media and their impact on privacy, politics, and journalism. The first volume explores the role of this technology on national and international security. Volume 2 focuses on the individual as both a producer and consumer of internet content, showing how the media itself is changing notions of self-identity, relationships, and popular culture. The book's content covers such topics as individual and community psychology, citizen journalism, and corporate technology.
