If I can ask my phone where I lost my keys, and it tells me where they are because of this technology, then that is awesome.
The only people that should be afraid of Google (and the NSA) information gathering are terrorists and pedophiles, so if you don't count yourself part of either or those groups there is nothing to worry about.

Don't see the value of privacy, huh? Fine. Post your bank account, PIN, and all your credit card info here if you really believe that. Throw in your logins and passwords for all the sites you frequent too as well as your personal contacts, your social security number and tax returns.
I mean, why not, right? You say the only people concerned about privacy are criminals and unsavory types. So prove it. Post all your personal data right here, right now.
