This is the first collection of readings on computer-mediated communication focusing exclusively on interpersonal interactions. Examining messages exchanged via email, Twitter, Facebook, websites, and blogs, the authors analyze communication issues of ongoing importance in relationships including deception, disclosure, identity, influence, perception, privacy, sexual fidelity, and social support. The book examines subjects that attract intense student interest - including online performance of gender, online dating, and using computer-mediated communication to achieve family/work life balance - and will inspire further research and course development in the area of computer-mediated communication in personal relationships. Because it provides a synthesis of ideas at the nexus of interpersonal communication theory and computer-mediated communication theory, the book can serve as a textbook for advanced undergraduate as well as graduate courses.
