This document summarizes key points from Chapter 3 of the book "Hanging Out, Messing Around, and Geeking Out" regarding intimacy practices among teens using new media: 1) The most popular methods teens use for intimacy are cell phones, instant messaging, and social networking sites, which allow easier communication than face-to-face interactions. 2) Teens are reshaping dating and romance norms by incorporating new media into their practices in ways unknown to adults. 3) Breakups can be difficult in the new media age as exes may still be connected on social networks, leading some teens to post about their new relationships or lives to communicate indirectly with exes.
