Alter Ego-Surfing

I've done ego-surfing — googling my name and turning up matches for myself and a number of other Ben Karlins (in today's search I don't appear until the 13th match). This time I needed a friend's email address so googled him. Nothing. Of course his name is out there. I just needed to know where to look although I still haven't got an email address. Guess I could call and leave a message on his machine.
