I also don't track users at my sites except for anonymous cookies on my cooking web site. The cookie lets me identify them anonymously so I can keep track of food they have on hand for suggesting recipes.
I put a lot of work into my sites and the really large payoff is meeting people with similar interests and also people who might want to use my consulting services. It would make me sad to have to abuse people's privacy in order to make a living. (I am contracting at Google for a while, but I generally think that mostly Google falls into the good guys camp, as opposed to Facebook - just my personal opinion.)
