You know that little globe icon on the Facebook website that displays your pending notifications? Of course you do. Well, did you know that the globe looks different depending on where you are in the world? The default icon portrays the Americas.
Facebook has quietly introduced a new icon for its desktop users in Europe, Africa, and Asia, which shows the globe from the other side. Log in from any of those continents, and you’ll see this icon instead.
