Making Rules, II: What matters is the first point. (Forgive me, but the others are red herrings, even if you’re an entrepreneur hoping to make money on the advertising gravy train.) Facebook crossed a line here. They lured us into a vast stockyard, and then began to monetize us in ways that violated our quaint notion that we are not in fact cattle.

Treating users of free services like cattle is as old as TV, radio and billboards. It may be as old as people painting in caves with charcoal and spit. The difference now isn’t in Facebook’s manners, which are no different than those of NBC or the New York Times. The difference isn’t even that this time it’s personal. That’s been a holy grail for advertising since the beginning as well. Facebook is reaching for a golden ring here, and I’m inclined to forgive them for doing that. [A must read about marketplaces and understanding our role in it (or what our role should be).]
