A New York Times article on college drinking includes this tidbit:
But no matter where the drinking is done, the morning after is often the same. Tracy O’Hara, 21, a Cornell senior, said: “I can’t imagine what it was like before Facebook when you could just spend the morning after a big night out recovering. Now you have to spend, like, an hour untagging photos. And then you read your texts and you’re like, ‘Oh, so that’s what I did last night.’ ” (It’s job-recruiting season, which means even most students who can drink legally untag every photo, she said.)
There’s some other interesting stuff in there too, like how college bars are dying because of social media. You used to go to bars to find everyone and meet people. Facebook makes that easier, and with text messaging, you know where everyone is anyway. And if a bar is slow, it’s less likely to pick up because everyone will text their friends and tell them not to come down.
