>tldr; Facebook is finally coming to an end. Their executives know this better than anyone, so they're scrambling to pick up as many scraps as they can in order to delay the inevitable.
Facebook is the Microsoft Office of social networking.. at least in "coolness" factor. Folks under 25, 30ish years old, pretty much only use it because they have to, not because they want to.
