Excerpt:

“Google’s Ads Preferences believes I’m a guy interested in politics, Asian food, perfume, celebrity gossip, animated movies and crime but who doesn’t care about “books & literature” or “people & society.” (So not true.) Yahoo! has me down as a 36-to-45-year-old male who uses a Mac computer and likes hockey, rap, rock, parenting, recipes, clothes and beauty products; it also thinks I live in New York, even though I moved to Los Angeles more than six years ago. Alliance Data, an enormous data-marketing firm in Texas, knows that I’m a 39-year-old college-educated Jewish male who takes in at least $125,000 a year, makes most of his purchases online and spends an average of only $25 per item. Specifically, it knows that on Jan. 24, 2004, I spent $46 on “low-ticket gifts and merchandise” and that on Oct. 10, 2010, I spent $180 on intimate apparel. It knows about more than 100 purchases in between. Alliance also knows I owe $854,000 on a house built in 1939 that — get this — it thinks has stucco walls. They’re mostly wood siding with a little stucco on the bottom! Idiots.”
