Wait. Why the fuck haven't any of the smart Alecs at Google, Facebook etc. thought about letting people willingly divulge their interests and things they're likely to spend money on? I mean, instead of trying to guess who I am or what I like, why not just let me TELL you? Let me provide some criteria (“pixel art”, “chiptune music”) and feed you some examples (Fez, MegaMan) and try to show me similar games. Then I might actually spend some money on a purchase solely because of an ad for once. For all the BS about personalized ads and shit, I have yet to see an ad for a product that I loved and didn’t discover through chance or word of mouth. Meanwhile if I search for a coffin even once Amazon keeps recommending more to me. This shit ain't working, unless the actual objective is to just track people and build "profiles" anyway.
