The New Yorker has published a lovely essay by Emma Rathbone, Before The Internet.
Before the Internet, you could move to a new state and no one at school would know anything about you. Youâ€™d have no online history. You could be anyone. You would lean against the lockers with a faraway expression on your face and let people assume whatever they wanted. Like that you were a girly girl but could also be a tomboy. Or that back in your home town youâ€™d been friends with a bunch of crows.
