How many pr10 sites do you know? As of now i know, Google Statcounter Im surprised that MSN and Yahoo didnt make it to PR10. How come Google is a pr10 site, who actually links to Google?
These are all the ones I know about... http://www.google.com (plus Google sub-domains, groups.google.com, froogle.google.com, etc.) http://www.statcounter.com http://www.apple.com http://www.adobe.com (plus Adobe sub-domains, partners.adobe.com, store.adobe.com, etc.) http://www.macromedia.com http://www.real.com http://www.whitehouse.gov http://www.nasa.gov http://www.nsf.gov http://www.energy.gov http://www.ercim.org http://www.firstgov.gov http://www.keio.ac.jp http://jigsaw.w3.org/css-validator http://www.w3.org Or as teckie said you can check out Wikipedia, or you can also do a search for pr10 list on any search engine and find tons of sites which list them.
