I mean... you take the good with the bad to get the breadth and depth in your platform. You make a shitload of money on PewDiePie and nothing on Mieleman (sorry; I forget the name of the German guy who posts videos of washing machine cycles), and balance the two. It's not difficult.

~~Okay then, 15 billion in profits last year. I'm no businessman but to me that's pretty damn good profits with those revenue numbers.~~
