Think about it. Tweeting is not really communicating it is just letting off steam. It has no immediate value, has no on-the-spot response from a foe, or friend, or other individual, it is meant for no-one, and everyone. It is a dumb idea. That doesn’t mean it isn’t popular, it just means that a lot of people like dumb things.
Trump tweets a lot because he eats a lot of food which cause gas apparently.
