Teens and Facebook: Research study agrees with conventional wisdom.

From the Guardian:

Teens do not care that alternative services are less functional and sophisticated, and they also unconcerned about how information about them is being used commercially or as part of surveillance practice by the security services, the research found. 

"What appears to be the most seminal moment in a young person’s decision to leave Facebook was surely that dreaded day your mum sends you a friend request," wrote Miller.

"It is nothing new that young people care about style and status in relation to their peers, and Facebook is simply not cool anymore."
