I will invite them in, mostly because of that last paragraph (well, 2nd to last paragraph counting that last sentence)... whenever I get a home. Efficiency!

I still don't understand the harm from them knowing more about my behavior, since this knowledge would ultimately save me money/make life more efficient. Sure, companies like Amazon and other retailers manipulate behavioral data so that I spend more money... but, so what? Are you saying these companies are going to coerce me into bankruptcy against my will? That they're going to form megacorporations (techcrunch.com), build (www.theatlantic.com)robots (articles.latimes.com), and take over the world (googleworlddomination.com)?

I'm pretty sure this is ultimately ideological for you, and perhaps I'm missing something about how this is going to subvert the control I have over my own life (or something) and turn me into a pod-person. But I will say my life is probably easier now than it's ever been, in many ways thanks to services provided by Google. And I've never had to pay a cent for anything from them (and their ads are perhaps the least annoying on the internet). And they are coming up with some really (www.npr.org)interesting ideas.
