Also, it's still up to you to call your mom, meet up with old old friends once or twice a year, go out to your hometown bar the night before Thanksgiving. Facebook doesn't take away those "moments you'll never remember with the friends you'll never forget." It just lets you keep in touch with those who might otherwise have dropped off the face of the earth. Don't blame some "social media". Also, kids these days, are just kids, let them socialize, it's probably not any worse than video games or TV, and you can't stop adolescent girls from gossiping, even if you take away their text messaging.
I think the only contradictory point Id make is that Facebook (and other networks) makes it convenient to get lazy and boil more of your relationships down to just being digital which likely degrades the meaningfulness and quality of a relationship. For example, talking to or going out with a friend is many times triggered by wondering how that friend is doing or whats new. Facebook removes or degrades that trigger in that you can find out whats new with your friend through their profile without any interpersonal contact.
Now (while again I completely agree that we as individuals are responsible for ourselves) on a macro level when you have billions of people being nudged toward this direction Id say it does create a pretty significant impact on the overall level of quality relationships within our society.
I wonder if it's the same thing with Facebook and other social networks. By "socializing" on FB the brain gets the same kind of high as if you had actually spoken to the person, thus making you feel satisfied with the social interaction so you don't seek them out.
