If Google’s so smart, why are its ad links so stupid? I noticed this morning that one of the Ad Sense links in the Google box on this page read “Sexy Girls & Sexy Guys.” That seemed kind of odd, given the depressingly nonerotic content of this blog, but then I realized that in a silly aside in my last post I used the word “thong.” Bingo. Such mismatches aren’t unusual for Google’s much-vaunted ad-serving service. In fact, it often seems almost entirely blind to context – like an idiot savant. That’s a vulnerability someone should exploit.
