Earlier quoted context omitted.
Facebook is giving you the illusion of having relationships and appeals to some nostalgic programming in our brains. I have a once close friend who moved out to Oregon from the east coast. I talk to him every two years when somebody dies at home. Knowing that his kid won the pinewood derby doesn’t give us anything more in common.
What is an "illusion of a relationship?" If you think of someone and appreciate the little bit of their life story they shared on Facebook, is that an illusion? After all, that's what relationships in real life are built on as well: telling each other what happened at work, about that new restaurant you went to, the joke you heard, the stupid thing your kid did. Facebook is a pretty good vehicle for doing those thing…
Whatever it is, it’s not a substitute for real two-way interaction. Meaningful relationships don't survive on impersonal status updates broadcast to a general audience.
If it involves communication back and forth (e.g. telling each other what happened at work) that’s something. If it’s scrolling passively through status updates or photos, or posting updates on yourself to nobody in particular, it’s junk food.
