In the last few day, I notice that some UK sites that ranks very highly for some keywords in Google.com are not ranking well any more, not that they have been lowered or anything but I think Google is just separating UK contents from US more and more
One good example is that I never rember GKDs forum's url (because of the hypens) so I just type in "it support forum" he used to be number 2 in Google.com but he is not any more, but he is still number 2 in Google UK.
Same for my webdirectorylist.
At the moment its just one way (UK sites downgraded in Google.com but US sites have not been downgraded in Google.co.uk
