Aww darned... it looks like I may need to re-tile my roof. I just checked Google maps and can see a missing tile. What's Eric Schmidts home address, I want to check his roof too, he's a busy man.
It's not a far stretch from that to seeing a picture of his daughter/son(if he has one) online and getting a layout of his house to plan an abduction. I'll be able to use his freely given personal information to see if he's home, perhaps pretending to be a wrong number with a quick honk of the car horn to see if I can hear that horn in our conversation. No horn = he's not home... or maybe he likes 4square and I can track him even better.
See where this is leading? One person with bad intentions can make for a very bad day, just ONE person. Google then must record all searches and activities in order to prevent a criminal, scratch that they can't, in order to catch a criminal after the fact. When you make it too easy bad things happen, including needing to make it even easier by collecting more, more, more.
This is the end of discussion for me, Google wants what they want but it's just not in my best interests to parade in front of millions of people unknown to me with everything about me in the wind. No thanks, it's my constitutional right to have an expectation of privacy which Google makes extremely hard to maintain. Now I'm off to fix my roof, I'll wave to you while I'm up there.
