You tried adobe.com it must be a PR10 for sure And herez to satisfy your curiosity http://www.seocompany.ca/pagerank/pr-10-pages.php
Here are a few more PR10 sites: www.w3.org www.adobe.com www.nasa.gov www.apple.com www.intel.com www.nsf.gov www.energy.gov Soo Google is not alone
there's also ibm.com funny how bbc is only pr9 whilst nytimes is pr10 - I know which I think has a greater reach.
a fair few have it www.statcounter.com www.whitehouse.gov www.ercim.org www.keio.ac.jp to add to the list
PR10 is mostly given out to big companies etc Can we really work out anything above PR7 ? I've never seen a DP member having above PR8
yup i heard there used to be around 100 pr10 sites but google changed it to make it harder hence sites like bbc.co.uk and google.co.uk are 9. If you look at sites that have pr9 & 10 you start to notice that they aren't really sites that care about pr but sites that provide either a service or lots of quality info so generate natural links which is what google wants to reward pr for (rather than people buying links or signing up to thousands of directories).
I started the same thread a few months ago. Ended getting an infraction and thread moved to seo cause the mod said it doesn't have anything to do with google.
Now that would be a time killer. PR10 may be assigned manually, could agree with that. PR9 and lower, however, don't think so.
