The regression models that Facebook and Google use to predict......
What exactly?
I told FB i like Joni Mitchell a few years back, and have told them very little else about me since. so now, dutifully every other FB page load has a little ad exhorting me to buy 'blue' - something i have done a few times since 1970 - but no so much since i got the cd in the mid 80's and ripped it to mp3 in the 90's.
2 weeks ago i filled out a new 'scrip for specs and, somewhat stupidly (i was trying desperately to find a pair of frames that didnt make me look like that uber-twat gok wan) i gave them my email addy. now i get an ad for varifocals along with my joni - blue ad.
could someone please explain to my just exactly how there is 'value' in knowing my purchase history if all it is used to do is generate ads for stuff I ALREADY HAVE??
and dont even get me started about the time i bought a sat nav and camera of amazon... 3 years later and they are STILL suggesting cameras and sat navs i might be interested in - admittedly both have been replaced since then BUT NOT AT AMAZON and not the week after I bought the fucking things.
Its nice that we get to play with sites like FB and we certainly wouldnt be able to do so without the massive con these guys have pulled on the ad wankers, but surely one of these dickheads is going to notice that the emporor is naked some day soon?
