I just finished Super Cruncers by Ian Ayres. Interesting book. He describes how statisticians with large databases are changing the world in many different fields. There probably isn't anything in the book that will make anyone a better handicapper or bettor, but I think it is useful to read about what other people in other fields are doing. It opens up a few pathways of thought. I recommend the book.
Note: one thing I didn't like about the book was how Ayres presented Justin Wolfer's work on college basketball. I won't get into that today and I may never get to it, but just wanted to note that in case someone read the book based on this recommendation.
