The Google software, in all its finite machine-code wisdom, can be severely retarded. Consider this context-sensitive text ad:

Just when I was thinking of buying some of that used EXPLODE stuff. You know how useful past kinetic energy can be, lacking existence in the presence and all.

Perhaps it’s an awkward metaphor for really bad software (so bad that it’s destined to crash), or broccoli-encrusted 7-bean soup (which ends badly no matter how careful you are). Or maybe software just isn’t that smart yet …

Of course the Google adwords stuff is dense, here’s another great example …

I’d say that eBay is paying too much for their advertising. Their ads look absurd on many of my daily searches on Google. Is that good business?
