Book excerpt: People ‘overshare’ when they interact with others through the screens of computers and smartphones. Oversharing means to divulge more of their inner feelings, opinions and sexuality than they would in person, or even over the phone. Text messaging, Facebooking, tweeting, camming, blogging, online dating, and internet porn are vehicles of this oversharing, which blurs the boundary between public and private life. This book examines these ‘presentations of self’, acknowledging that we are now much more public about what used to be private. With this second edition, Agger adds a new chapter on whether privacy is possible that addresses selfies, job loss due to oversharing, the surveillance state, and examples of when the private should go public.
