I'll add to the pile of speculation of "I know why facebook is failing (when it isn't)". To me it's the fact that it became less and less of a useful tool. It used to be this simple thing where you could connect with your friends or people you would meet (perhaps with the intent of dating them). There was a news feed that was sorted by chronological order, and you would mostly see updates and photos posted by people. Creating an event was easy. Today, nothing is chronological, profiles are (somewhat) public facing, people just posts links, photos has basically moved to instagram, messaging has moved to whatsapp, and events hasn't changed a bit. Plus there's a ton of other new features that dilute the tool.
