Im not sure how much PG's issue over privacy is a problem.
My thoughts?
1. The local advertising in GMAIL and sites with adsense come from a piece of javascript that looks for related words and matches up adverts with that. I doubt there is any privacy concerns
2. I havent checked Google Privacy Policy but I suspect it fully addresses how they handle privacy. A company like this doesnt get to where it is today without being on the up and up.
3. Even worst case scenario, Google doesnt address this in their privacy policy and they are using this information. The shear volume of information is so overwhelming that they could only use this to gather general information about a range of issues. I highly doubt any of us are important enough as an individual for Google to care about and go tell our moms about all our sins.
