Who’s the most influential world leader? It’s a debatable point, but you’d be hard-pressed to find someone more influential than U.S. president Barack Obama. Obama, of course, is on Twitter – and has been for some time – so by definition he must be the most influential head of state on there, too, right?
Wrong. At least according to one new study, which suggests that it’s Pope Francis who is actually Twitter’s most influential world leader. Pretty good going, when you consider that “he” has only been tweeting since last December.
