I find the iMessage dots feature incredibly useful. The dots let you know if the other person is typing, which tells you several important things. Number one, you know that the other person is in the middle of typing something so you don’t leave the conversation. Two, it prevents you from interrupting him or her before that person is done saying their things. Three, it is also an indicator that the person has read your texts and has began to respond.
I appreciate this feature because as someone who has the tendency to interrupt a text conversation, the dots bubble lets me know the pace of conversation.
