Interesting commentary on the fact that user data is rarely, if ever, expunged from the system. Residual search information is logged and compiled but never really sifted for outside factors. For instance, if you’re searching for a gift for your child or your spouse is using the same computer. The result is a blended “persona” that has some features of multiple people. I suppose it is better than nothing, but there has to be a better way to compile the information and eventually to purge it when new info replaces old. My kids are small, I’m not going to be buying diapers forever.
