Amazon Recommendation Profile

This morning I received a recommendation from Amazon for:

Draft Horses and Mules: Harnessing Equine Power for Farm & Show

It's interesting to think what each person's Amazon recommendation profile says about them at that time in their life. It would be neat to look at your Amazon recommendation profiles over time and see how they change with life changes. Amazon offers a categorized summary of its recommendations if you click on the "See more recommendations" link. My list is currently:

Camera batteries: 3 items
Classic cars: 5 items
Communications: 4 items
Customize: 9 items
Guitar: 15 items
History: 8 items
Instruction & Study: 12 items
Investments: 8 items
Management: 12 items
Marketing: 7 items
Memory Cards: 4 items
Native American: 13 items
North America: 14 items
Organic: 4 items
Popular: 3 items
Product Management: 3 items
Puzzles: 3 items
Real Estate: 12 items
Songbooks: 10 items
Sport Utility Vehicles: 6 items
Strings: 5 items
Techniques: 14 items
Theory: 5 items
Theory, Composition & Performance: 16 items
Woodwinds: 4 items

Seems like the accuracy of their summary is off, however, as if I inspect the list, there are also a considerable number of recommendations for farming and gardening books, and yes, books on babies...
