@Harp: I’m interested in the line between “can” and “should”. Yes, the information is publicly available and anyone can find it. But should you? If I wanted you to know this about me, wouldn’t I have told it to you?
So at what point is the right to privacy ceded? If someone from my past blogs about me using my full name, I don’t have control over that being Google-able. If I wrote a letter to the editor for a print newspaper once upon a time and that newspaper has been put on the internet, did I cede my right to privacy by putting it in print in the first place? And so on and so forth.
