I think it's funny the cities they included. So Bay-centric. I can't say I am shocked surprised or alarmed at this, this is information marketers already have about you and they have already been using for a while. They already have extremely detailed personal and psychological profiles on everyone. The most clear example of this for me was some years ago when my wife and I would receive what were essentially identical credit card offers in terms of the terms they were offering but everything about the marketing was totally personalized based on our psychological profiles. They know you better than you know yourself, they know what color envelopes you prefer, if you like a printed stamp or an adhesive one, what sort of fonts will appeal to you the most. All those things that people don't even think about consciously but they know about you. The good news with all of this is that the end game for all this data and analysis of us is just that they want to sell us shit. Worst case scenario is that you get advertisements delivered to you for products that you want with offers you find appealing and then you buy their shit. Shit you probably wanted anyways. Heck Amazon predicts what people will buy ahead of time and then stages those items at fulfillment centers near their house so that when they actually order the thing it is ready to go. The horror of getting what you want when you want it!
