Although I generally agree with the sentiment, I feel this is a sort of shallow glossing over of things; There are many ways to make gamification work and many ways to make it not work. Sebastian Deterding's talk on Getting Gamification Right does a really good job at explaining it. http://www.youtube.com/watch?v=7ZGCPap7GkY
I wholeheartedly agree with this statement. There may be instances where it is perceived as successful but it will always feel like clutter and noise to me.
