A little while back I was chasing some links and I landed on the amazon page of a book I like. It turns out that I searched this book in Amazon not too long before, but it looked different -- it had a lot fewer reviews. Then I realized, I was on the Wabi Sabi page of amazon.co.uk, as opposed to amazon.com Looking deeper, I realized the books other people went on to buy in the UK were more interesting to me than those Americans went on to buy. For sure there are many overlaps in the "Customers Who Bought This Item Also Bought" section, but there was also a sufficient number of differences. Take a look.
I've found that my reading tastes lean toward those in the UK, as opposed to here (US, Cambridge).
