any idea on how to find out pages with 10/10 PR ??

I know that google.com is a 10/10 but other then that.. .any pointers ??

Why did this search term hang on me .. are others noting the same sndrome ?

google.com/search?sourceid=gma ...

I think you can try this...
searchenginegenie.com/pagerank ...

Yeah, that page is your best start... tho you might want to ask their creators too how they found out about the site.

Another good approach to locate high-PR sites is to google for [www] or [http] and check some of the result sites...
google.com/search?hl=en&q= ...

Wikipedia used to a page that listed all/most/some of the sites that with high PR...
