It's an interesting point about not ever being able to escape your school mates. With Facebook, they can track you down after you graduate easily. That is a totally new thing.

Is it a good thing?

Sure, we get connectedness. But do you really want to stay connected to _everyone_? Facebook will kill privacy for these kids if we do not do something. They will never be able to "escape their past" in the way that earlier generations could. That seems unfair.

Food for thought.
