Re: Here's a thought, Amazon
It is hard to see anywhere on the Amazon website that has been improved by any of their inventiveness.
I quite miss the old days of seeing a list of decent recommendations on the Amazon home page; even when it went awry it was at least amusing: I was convinced that only one other person had bought a copy of (certain huge book) so I was getting suggestions for lots of maths monographs (interesting, but way above my A-level results) and just hoped (s)he was fascinated by C++ programming.
Then again, I spent far too much money when their recommendations were good, so the changes have been saving wear and tear on the credit card: that was their intention, wasn't it?
