Data points that Facebook uses to target ads
&quot;perfectly targeted ads&quot;? Never had that experience.<p>Even if I summarize all the analytics solutions out there, like ads, Facebook stream, Youtube, Amazon, Netflix. What they usually do is they figure out what I did in recent history or in general and present me more of that. I don&#x27;t know about other people, but that&#x27;s absolutely not what I want. That&#x27;s boring, or maybe even unnecessary.<p>Like, if I just bought a book about Linux system administration the only reason I would buy a second one would be because the first one sucked (and Amazon knows the ratings of the books). A reasonable suggestion after that would be something people do with Linux, like hosting a Wordpress blog. Honestly I might not even know what I would do with my newly acquired skill once I succeeded with that topic. Also it&#x27;s quite tiresome to learn. Maybe after reading 30% of it I would like to insert a simple but interesting novel or comic book. Why not suggest something like that to me?<p>Or I just watched an action movie on Netflix. Then I don&#x27;t need other action movie suggestions. After that maybe I want to watch a character focussed tv show.<p>What we need is not a &quot;I know what you did and here is more of that&quot; suggestion engine. What we need is a &quot;oh that&#x27;s getting boring, here is other awesome stuff that may surprise you&quot; suggestion engine. Figure out the stuff I don&#x27;t know I want and then suggest that.<p>And honestly, not a single of these billion-dollar-engines out there do that for me at the moment.
