I’m 16 and, unusually, I use Twitter quite a bit. I say unusually because perhaps you’ve heard that teens don’t tweet. This first came to light last year when a 15-year-old Morgan Stanley intern wrote a report [PDF] where he explained that teens “realize they are not going to update it,” and that “no one is viewing their profile, so their ‘tweets’ are pointless.”
Teens’ lives are entirely built around their actual friends. Quite simply, why would teenagers bother using Twitter when Facebook exists, and offers so much more? Teens want a platform that allows easy, fully-functional communication to an exclusive social circle. That is, solely to their friends and peers. Twitter is a platform built for inclusive broadcast (to everyone), and to teenagers it offers no obvious value.
