Amazon.com is at it again, recommending products that I will be sure to enjoy based on 45 CDs that I have ranked. Using all this data and the best algorithms in the business, Amazon has recommended that I read this book, a coming-of-age sisterhood novel about four young women and a pair of magical jeans. Is this really the same audience that listens to the music that I do? Which part of "male who likes The Smashing Pumpkins, Zebrahead, New Found Glory, MxPx, and Juliana Theory" translates under data analysis into "would be interested in reading books with a target audience of females aged 10-15"?
