There’s an old saying in Computer Science: Garbage In, Garbage Out.

 

Amazon has just provided me with a perfect example. Because I’d bought a book on cosmology, I received an email recommendation from Amazon today:  

As someone who has purchased or rated Bang! The Complete History of the Universe by Brian May, you might like to know that Parker’s Encyclopedia of Astrology is now available. 

Er, no, I really don’t think I would like to know that, or have the slightest interest in purchasing the said item, thank you very much. Obviously, there’s a muppet somewhere in Amazon who thinks that Astronomy is the same as Astrology. Well, one is science and the other is bollocks, sunshine.
