Google privacy: A user’s guide

Google Inc. knows more about me now than it did yesterday. I don’t much care, but that’s just me.

It will compare your Google Web searches with the YouTube videos you’ve watched, your messages on the Google Plus social network, and the smartphone apps you buy in the Android Market to create a remarkably detailed dossier on your tastes and habits - which it can then use to better target the advertising it sells.
