I shop at Amazon quite a bit. They have more information about my purchasing and browsing habits than they could reasonably need, plus the same data on millions of others. On top of that, when I visit their website, they know I&#x27;m already there to spend money. Amazon&#x27;s front page should be the absolute pinnacle of targeted advertising.<p>And yet, if I buy a coffee maker, the front page is covered in coffee makers for weeks. I&#x27;ve never bought anything based on what&#x27;s on the front page and I&#x27;m not sure I&#x27;ve ever even clicked those suggestions. I&#x27;m sure targeted advertising can work in the long run, but at the moment the success rate seems so low that it&#x27;s more often an annoyance than a convenience.
