Thanks for this article, ulfstein. One thing I'm on the edge about is flattening the crowd so that no one person or group of people have more of an influence. Although every opinion should matter equally there is always those people that know more about a topic. Those people should have more of an influence in the overall market. Good read though!

I agree. I've not yet had a closer look a the sites mentioned but am wondering whether any of them might employ such a system.
