Pretty Cool, a UK version anyone?

This site looks pretty cool but does anyone know if there is a UK version?

I noticed that the site is in Beta.

Under FAQs, I found this factoid (http://www.quantcast.com/faq.jsp#Do_you_cover_the_whole_world.3F), but do you mean "does anyone know of another site like this that covers the UK?"
