In just a few short days, Yo has climbed to the top of the app charts, accumulating some 50,000 foolish users who send the same dumb salutation back and forth to each other. Stephen Colbert asks the right question in this hilarious clip: "Y?"
I'll admit that Yo has its charm. It's kinda funny! But it also fails to communicate anything useful or even the most basic emotion. It's so flat it makes text messages seem like sonnets. Imagine getting fired or breaking up with a "Yo." You can't because that would never happen, yo.
