So now instead of not finding what I want, I can not find what a celebrity wants. Awesome!
In a way, on an abstract level it is sort of cool. That's basically enabling to run searches as someone else, enabling you to see things through another person's eyes. As for myself, I'd consider it interesting to see statistics based customized searches. We already know google uses records form past searches and clicks to determine what to show us in subsequent searches. What if you could, run the search and see results that an average Finn would? Or an average Ethiopian? Or an average Ethiopian woman, who's interested in technology and cats? I could see some, especially marketing related applications to this. How to optimize my website, so that people in my target group will see it as her first search result, for examle.
