Want to show that the art of sincere, thoughtful communication is dead? You only have to take advantage of a little-known (but recently discovered) Facebook feature. The social network has been quietly rolling out SMS birthday notifications that let you wish a generic "Happy Birthday!" simply by replying "1." Yes, you too can reduce an important milestone in someone's life to a single-digit text reply that takes less effort than it does to unlock your phone. It's true that this could come in handy for the birthdays of Facebook friends you barely know, but we'd say that taking the few seconds extra to write posts on their timelines would be infinitely more considerate -- you're never in that much of a hurry.
