I think there is definitely something to this. In the show Top Gear, we see celebrities competing for the fastest (or maybe most entertaining) lap time in their reasonably priced car. I love seeing how they will compare, even if, as an American, I don't quite know who all of them are.
But what if Top Gear created a service where people could show up and pay to drive this car around the track to see how they would compare with these celebrities? How fun would that be? Look...I've got the exact same time as Mark Wahlberg! I'm as fast as he is!
So, well, this example wouldn't happen. But, as an avid gamer, whether it's Call of Duty, or Desktop Tower Defesne, or any iPhone game, it would be quite fun to see what celebrity I am on par with.
I love this idea and could totally see it work, whether as an independent business idea or folded into Xanga or any game development studio.
