This is most likely just another way for Google to build a profile on you for advertising purposes. What better way to target site advertising than to ask you to rate the sites that come up?
I am able to get it where i am located (mid west usa) but im not sure if all users are able to see the google searchwiki yet. If not there is a video and some screen shots of the searchwiki at http://www.thesearchwiki.com do you guys think this will take off? do you think it will effect the google search results alot from now on?
Actually, I have put my gmail theme as planets. It's actually a little easier on my eyes then the default bright white one.
Really cool ideas about the searchwiki. I like it.
