Data Mining Amazon.com Wish Lists

Dr. Webster writes "In his article "Data Mining 101: Finding Subversives with Amazon Wishlists," Tom Owad of Applefritter outlines a way in which one could build detailed personal profiles of hundreds of thousands of U.S. citizens in a matter of hours. Reading habits, personal tastes and even political party affiliation could be inferred from the results, and through the use of Yahoo! People and Google Maps, one could even map out geographically where people with certain interests or affiliations live, down to their address. Most surprisingly, the process of doing this is completely legal, and doesn't even violate Amazon's Conditions of Use."
