This is a pretty interesting read for us old people.
In short, many have nailed this on the head. It’s dead to us. Facebook is something we all got in middle school because it was cool but now is seen as an awkward family dinner party we can't really leave. ... That being said, if you don't have Facebook, that’s even more weird and annoying.
What I find most interesting are how people manage the glut of social outlets. Previously we had three ways to communicate: Write a letter, make a call, meet in person. Now we have a hundred different ways. I think I still prefer email.
