I was somewhat startled to discover that Kindle reviews on Amazon.co.uk do not materialise on Amazon.com - I'd assumed (naively) that both sites took any reviews that were going. Apparently not. Effectively, if you want a review to show on both, you have to post it seperately on each location.

Strange - apparently, Amazon reckons that English and American outlooks are different enough that we will not want to see reviews from our cousins across the Atlantic.
