Nathan Yau over at FlowingData is absolutely correct. This is the best statistics question ever. Right now, Nathan’s post has 721 comments. That’s after only two weeks. To that you can add the 217 comments on Raymond Johnson’s original post on Google+. A post that has also generated 1,449 shares – undoubtedly with a loooot of comments as well. And no one seems to agree much.
The answer? I’m pretty sure it’s 0%.
