Mashable's Ben Parr points to new data showing how teenagers tweet much less than adults:
Twitter’s different than Facebook or MySpace because Twitter is not about your friends. As I highlighted in my analysis of Twitter’s new homepage, Twitter is quickly becoming the epicenter of world events. Yes, you can update your status, but you can do that just as easily on Facebook. What you can’t do on other social media sites is learn about the #IranElection crisis in real-time. But does this really interest teenagers? Teenagers are notorious for being terrible at social engagement, voting, and keeping up with the news.
