> What teenager wants to hang out in the same place as their parents?

Parents have been on Facebook for a long time. Why are teenagers today leaving but not teenagers from 3 years ago?

Also, why is it assumed that teenagers who stopped using Facebook today aren't going to come back when they get older and have adult-things they want to share?

ahh, it's not that the teenagers are seeing adults share things and not liking what is being posted, it's that people are uncomfortable posting things because other people may see them.
