lol. I think it's kind of creepy. Almost as creepy as the "Missed Connections" section of Craigslist.
Personally, I'd want someone who had the balls to talk to me face to face and not run home to post on the computer or somehow find out my work number and call me.
Not finding anything about someone online doesn't mean anything. I'm an internet addict and you won't find anything on me either. Kind of creepy to think of random people Google searching ya too. :P
