I'll echo the sentiment.

Google is a wonderful tool, but could be extremely dangerous in the wrong hands. Be careful.

An example of my worry: my friends and I once, after having watched one too many James Bond films, decided to test our tracking ability. We had a person's home phone number; nothing else, not even his name (he'd called my friend's cell and she didn't recognize the number). Google provided with his name and home address; Google Earth provided us with a satellite image of the street. The man's wife told us, when we called to see why this man had called, that he was in the pool and asked if she could take a message; that one word, pool, lowered the number of potential houses to two.

Not everybody has collegiate curiosity as an explanation for their lurking. Be careful what information you offer.
