With June 27th PR update, it seems Google got bitten by its Panda and its PR is 9 from original 10. Also with so much content being generated on Facebook, its PR is 10
Look at these stats taken today:
google.com – PR 9
google.co.uk – PR 7
google.co.in – PR7
google.co.jp – PR 8
google.de – PR 7
google.fr – PR 8
Facebook – PR 10
Dmoz dropped to 7
Whitehouse.gov dropped to 9
Its funny though however most of the Google sites lost PR!
