iMessage and Facebook messaging have all started to automatically notify users when the person on the other end is typing. Why? Because it forces you to hurry up and finish your message. Supposedly, it helps to make text messaging more like a real conversation. (Sort of.) Instead of being piecing together and editing a super important text to that special someone, you're going to have to think fast when your fingers hit that keyboard, since the other person can see when you do just that.
