This is an infographic based upon a recent Pew survey of teenage social media usage. The insight that received most attention from that study was that teens are increasingly disillusioned by Facebook. This infographic points out what I found to be the most illuminating statistic from the study: Facebook use is higher with teenagers and young adults than with any other age demographic. Of course this doesn't qualify how they are using it, but it substantiates some other insight (Stephen Wolfram's data comes immediately to mind) that shows that everyone is so invested in Facebook as a utility that there really is no comparable social network.
I'm curious to know your thoughts about this infographic or Facebook and teenagers in general.
