I love Amazon. They contribute literally pennies to the running of this site. Let's put it this way, I've never actually reached the threshold for getting even an Amazon token from them from people clicking the links on this site.
Nonetheless, I use Amazon a reasonable amount, and they send lots of email advertising as a result.
One particular type of email is the "recommends" email, where Amazon examines what you've bought in the past, and looks for patterns amongst its other purchasers to perhaps direct me to another title I might be interested.
Except it never really works that well. I'm sure that there are teams of people in the States who sit there fine tuning Amazon's algorithms but basic things like books I bought as gifts rather than for myself are difficult to take into account.
Anyway, this a rambling way of telling you about the book I was "recommended" today. I bought Mission Song, by John Le Carré a while ago, and so I was sent this:
We've noticed that customers who have purchased or rated books by John Le Carre have also purchased An Introduction to Godel's Theorems (Cambridge Introductions to Philosophy) (Cambridge Introductions to Philosophy) by Peter Smith. For this reason, you might like to know that An Introduction to Godel's Theorems (Cambridge Introductions to Philosophy) (Cambridge Introductions to Philosophy) is now available. You can order yours for just £42.75 by following the link below.
Wow. That'll go down well with people who love spy-thrillers.
I did study maths at university and am vaguely familiar with Godel and have heard of his incompleteness theorem. But seriously, this is a little specialist for the average reader.
