For an app that a billion people use, you would think that it would figure out how to do notifications better. Nearly every notification that comes through, it comes through twice. And if you click on one, and then the other, one stays "unread". Yet at the same time, so many of my friends posts, never even pop up, even if they are in my favorites list. Yet Schmuckerberger is worth 100 billion bucks. Reinvest in to your money maker, before it becomes a money shaker!
