The simple solution to anyone concerned about this is to just stop using Facebook. I've done so and it turned out to be a great decision. Contrary to the belief that you'll be "left out," people can and do get in touch with you for the important things. SMS, email, phone, snapchat, etc all work really well today, and you can get your social news fix from reddit, HN, and elsewhere if you need it. I've gotten measurably happier and more productive once I stopped using FB completely and haven't lost touch with any of my friends.
