Another bad analogy. 1) In public places I usually speak at the volume level at which others can't hear me; if I start yelling in a public place I should expect things that I yell to appear on youtube, in the local newspaper, in the police log 2) I come to the restaurant to eat. If after eating I fill out a survey which includes lots of personal possibly identifying questions, would I have the right to be surprised if next day I find my answers on the website of the restaurant? Have I read the fine print on that survey?
