The Macdrifter doesn’t (wholly) agree with my assessment that Google’s selling of tablets for cost is a bone headed move, saying:

>Build a logical model of how you make decisions and sell ads to leverage that model. It’s simple and lucrative.

Except that it is short-sighted. Because showing someone an ad doesn’t make the ad effective — what makes the ad effective is showing someone an ad for something they are preparing to buy at just that moment. That’s why ads on Google Search work really well, and the AdSense ads on the sides of crappy blogs make the site owners no money.
