There's that, too. Too much information floating out in cyberspace, and too many people looking to exploit it for profit.
I worry about that, too. With all this data seeming to have a permanent life, it amuses me to think what future anthropologists might think about our “trivial” concerns. I’m not sure I like being considered quaint!
I want do this kind of survey because I am not sure what will be done with the information. Could this be a plot by the insurance companies to jack up insurance rates? I prefer to check before I drive and leave this survey alone.
