People like to make so much of the Internet into an analog of the so called "digital town square". The irony is, in the town square, everybody can see you and know who you are.
Many are up in arms about "online privacy" forgetting that what they are really trying to do is make something that is essentially public private.
I've never been under the impression that anything I access via a web browser or other network service is anything but public. I've never trusted that Google or anyone else would protect my data and I don't create Internet artifacts that would embarrass me.
Look, would go around your neighborhood asking people about strange fetishes, your strange wart, or about anything else that you'd prefer people not know about you? No.
So why expect that every piece of information that you put on the Internet should be so guarded?
