I went and visited a friend the other day. I should mention this is a new friend who is a publisher and our meeting is a bit of a long story. But, after our visit I get this message on facebook saying something about a Bio. Huh? Bio? This friend went and looked at all my facebook posts and my website. Just with my posts and website she was able to come up with this amazing bio. I was and am a bit shocked at how much info she was able to pull together in the 15 minutes that she claimed it took.
My point, only put out on the web information you don't mind the world knowing about. Its stays out there for a very long time.
As far as macbruce's pet peeve, yes, location is very helpfull.....
