Any evidence the party is coming to an end? Actually for me it is getting a bit ridiculous when an app like Yo can get like a million dollars when it goes viral without anyone actually figuring out what's so great about it. It does seem like growth is triumphing over other metrics, like revenue, or common sense. Of course if we go by that measure, companies like facebook will never survive at all, not sure how this is gonna play out.
