i think you both are kind of missing the point. facebook knows when my friends get together and have a party. it also knows who my friends are, how we met, and where we grew up. so what? i put all of that information up there intentionally. if google wants to collect such information and use it to help me, and maybe put ads in front of me that may even be helpful, then great. i'll give them more information.
