Stalk-vertising.

Above is an online ad I saw recently heralding the virtues of some data company. I find this sort of behavior on the part of marketers Stalinist. Your every movement is being tracked and (in the parlance of today) monetized.

I call this advertising Stalk-vertising.

Facebook, as of a couple weeks ago, had a valuation of almost $510 Billion, and they claim 2 billion users. My math says, that means each user earns them $255. So, they're selling your data to marketers and making $255 on it, on you.
