Email suffers from other problems. Chat protocols have the ability to be either. It is a small act of violence to expect a chat message warrants an immediate response. To me, the most important feature of any messaging service is to queue up until I'm ready to respond. I'm either asleep or awake. And if I'm awake, I'm probably thinking of something else. It's a happier life if I finish that thought before starting a new one.
