Although it has not yet reached the level of "ruling the country by Twitter", it has indeed brought benefits to the country. The actual effect may be better if Trump is not willful to say whatever he wants. The benefits are at least as follows:
First, it is more direct and accurate to express his wishes to the people without "sending words" through the media.
second, you can directly see the reaction of the people and listen to their voices.
Third, personal opinions and ideas can be conveyed to the people more quickly and accurately. Speed up the flow of information and improve efficiency.
fourthly, it has improved the intimacy with the people.
Fifth, due to the universality and globalization of the Internet, personal voices can spread all over the world in a few seconds.
sixth, flexible, anytime, anywhere, anytime.
Take Japanese Prime Minister Shinzo Abe as an example. Before his visit to China, he sent a tweet at Haneda Airport. This tweet not only expressed his feelings, purpose, reason and goal of visiting China to Japan, but also conveyed information to China. Therefore, China media translated and commented on it and made extensive reports.
Although Twitter is small, fast and effective, it may become an indispensable tool for future leaders to govern the country!
