And frankly, Google should be one of the least of our worries. Unless you tell them, Google, Microsoft and Mozilla, for example, they don't know our real names, street addresses, billing information, or even our physical location if we connect via Ethernet. And they are not trying to collect that information either. The closest Microsoft, for example, knows of my physical location is my POP (point of presence) - the physical location where my ISP connects me to the Internet backbone. In my case, that is 6 miles away on the other side of town.
