There was a time when I felt pride in the fact that Googling my name threw up more than 50 results, and then the realisation struck that I was not private anymore. Anybody wanting to know about me can just google in my name, lo and behold! I am all there, naked. Blogging in my real name( even though I use only the first name, references to my blog with my full name) etc etc have made me more public. I can't do a Ctrl+Z to undo.
