Well there is bunch of situations where: I can ask something and if someone can answer immediately I am done. If I send the question and wait for response I waste time. If I send the question and work on it, I will be halfway done or in some other state then I got stuck so when person answers my request, it might not be a valid question anymore. If I start working on something else I break my context and sharing screen what else gets harder. When I ask "Hi are you there.", keep working on thing I am stuck I can ask more specific question when person replies, because then I might have checked two or more things. Most important thing is, if person does not reply, I am not getting mad or annoyed, she has more important things to do so OK.
