Facebook has recently discovered that beyond the uncanny valley of personalized marketing lies the bottomless pit of invasive identity misappropriation.
But there is a deeper problem here. I’ve said it before and I will say it again. Facebook has the data, but they do not have users with shopping intent. Nobody goes to Facebook to buy stuff. Facebook is for meeting friends, like a bar or a club.
Even with the best products in the world and the most detailed private information it is not easy to sell stuff to strangers in bars; unless you’re selling beer.
