Same as when I began writing in this space, when 2 + 2 was initially linked to by all sorts of drunken hockey loving retards, the motherfuckers at Google figure people who read the Dope City Free Press are simply dying to buy crap beer mugs; watch pitiful hockey soap operas on their giant tvs; quit drinking beer; drink more beer; smoke less dope; grow better dope.
That is the trouble with computers doing your thinking for you: computers can read words but they still have one fuck of a time with context. The human brain can understand that beer and hockey is the background, the sub-text, the hum of traffic on the street in my country. The real action lies elsewhere.
I gather the adverts Google puts on your screen depends on where you live. My mom lives in a town heavy with old farts. She has been seeing a lot of adverts encouraging she get her colon cleansed. I have yet to see that one which is too bad because my colon could use a good cleansing.
