Former PTA President and blogger KCH says: "Honestly, this train has left the station, and I don’t think it’s easy/possible to totally hide from someone looking for you."
Congress wants to regulate it, political campaigns want to control it, parents are concerned and regular you's and me's are unaware of how public information has become full of private matters-- free to remix and distort, copy and distribute, and impossible to keep private and controlled.
Your Personal Information is "out there"
From pending Senate committe concerns about consumer control of personal information and how much outsiders ought to be able to gather informatiaon, via NYTimes:
"...72% of Americans are worried that their online behavior is being tracked and profiled by companies. Many also overestimate the extent to which the law protects their privacy...43% of Americans "incorrectly believe a court order is required to monitor activities online." and 48% "incorrectly believe their consent is required for companies to use the personal information they collect from online activities."
Personal privacy is completely out the window (Googling someone is so last century). KCH writes in How Does Big Brother know so much? about how, as a parent and regular person, you should be concerned about what you can learn about people online and she writes:
Look up an address on Zabasearch (which claims three times more residential listings than the White Pages). iSearch claims to go beyond Googling and can find someone's age and address and relatives, schools attended and sexual orientation and social networks, including information on children and teens. For an extra fee, you can find out the phone numbers, addresses, email addresses and other background information.
I find this all very disconcerting and strange.
