I think this guy gets it: Staking Out The Far Edge and he predicts that President Trump will continue to twitter.
As to the tweeting of the Donald, there’s little chance that his style will become more “Presidential”. He used that style to defeat 16 Republican candidates for the nomination and to defeat Hillary Clinton. Yes, his tone may change, the Presidency has changed the tone of every man I’ve seen take on the job.
But the tweet is far too useful to Trump to ever give up. It is his direct connection to the American people, one which cannot be changed, misquoted, or slanted by the media whether favorably or unfavorably. In addition, he employs it as a most potent negotiating tool, using it to good advantage in a number of ways including staking out the far side of a discussion. So I expect little change in his use of Twitter.
