There is a difference between not grasping and not agreeing with a certain way of living.
Wanting to meaningfully share oneself with others is antisocial... okaaaay.
A facade. Worthless noise and baggage. I'm not sure if you were a grown social person before the internet existed, but it is really wonderful when the way people interact with you accurately represents their current role in your life. The congruity keeps things to the scale a single person can live up to, keeps the heart focused rather than scattered, keeps investments meaningful and impactful, and keeps community strong. We are meant to come and go from each other, we are meant to carry only a couple handfuls along with us on our ways. If we can accurately model the internet to the nature of humanity it is better.
"Before the internet" you probably lost contact with nearly everyone you went to school with the moment you graduated. I don't even want to think of what life was like before cell phones
The world has changed since then.
I'm "facebook friends" with people I've grown up with since elementary school. With people I met in college but won't see again. With coworkers from past jobs. Kids these days have friends on facebook that:
A) have moved across the country that they will never see again, or
B) have transferred to a different school.
For friend A, even though they will never see each other again, they'll remember each other. They'll watch each other grow up and see how they develop into young adults.
They'll congratulate each other when they marry and have kids because a mutual friend noticed and made a comment on his/her wall, and it happened to pop up on your feed, even though you haven't seen each other in 15 years.
For friend B, even if you're not in the same school any more, maybe the friends would like to catch up once in a while by hanging out at the mall or see a movie together. Or maybe not. Maybe they'll just post on each other's walls once in a while. Maybe they'll eventually remove each other from their friend's list. But all of the possibilities are there, because of Facebook.
This is why facebook is enormously successful. And whether or not you personally agree with that sort of casual relationship is completely irrelevant. People like you may prefer Google+'s private model of "close relationships only" but this type of thing is exactly what will determine its success or failure.
