I have googled myself before. I have a professional license which is public information, so that info is available. I have found some references to thank yous in books and articles from colleagues which I didnt expect to find.
Like Dapper, I too, have found a site that provides addresses and phone numbers, ages and persons in the household. That was disconcerting considering every address I have had since the 1970's was there.
I dont use fb or twitter or anything else that can blindside me with uninvited attention. After a few threats in child protection cases, I am extremely cautious using the net. It is too easy to track someone if you are so inclined.
I am also a compulsive cookie eraser after having ads specially tailored for me on certain web sites. That felt very bizarre to me.
After one too many crime shows, I am also very cautious when erasing things on my hard drive. I use secure deletion programs and regularly wipe the space as well. When I am totally bored, I have a program that will search the drive to see what info is still recoverable.
There is very little privacy left in the world and on the net without me leaving a digital footprint everywhere I go.
