When I think of someone who exhibits the behaviors of a great communicator I think of my Dad. The way he speaks to people draws them to him. He can walk into a room and not know a soul and be able to strike up a conversation with someone and continue the conversation. The behaviors I see it that he ask the people he is talking to open-ended question, he rephrase what they said and then inserts his opinion.
If I could communicate like my Dad, I would want to be able to communicate with others like he does. I would use his approach and be able to continue with a conversation with someone you just met. I do not want to have that uncomfortable moment when there is nothing to say.
