Who’s Driving Twitter’s Popularity? Not Teenagers - NYTimes.com
Many young people use the Web not to keep up with the issues of the day but to form and express their identities, said Andrea Forte, who studied how high school students use social media for her dissertation. (She will be an assistant professor at Drexel University in the spring.)
“Your identity on Twitter is more your ability to take an interesting conversational turn, throw an interesting bit of conversation out there. Your identity isn’t so much identified by the music you listen to and the quizzes you take,” as it is on Facebook, she said. She called Twitter “a comparatively adult kind of interaction.”
