Do you know who is competing with president Donald Trump on Twitter?
Lloyd Blankfein nobody else but the boss of the great and mighty global bank Goldman Sachs.
Twitter is not for girls and boys, for petty news; Τwitter has become the news network of the world.
I must confess that this may sound as a slight exaggeration, but when the banker writes about his gloomy prophesies for Brexit, the British Prime Minister, Mrs May, responds. This means a medium. Twitter has become one.
