Funny that this discussion would come up today since just last night a girlfriend and I were IM'ing about this very thing. She had googled my real name looking for my website, and we were laughing at all the people there were that shared my name. Then I googled my screen name and it's almost allllll scrapbook related stuff...18,300 of them...yeah, I'm active online!

the last few were funny though because they are in Arabic...Arabic writing and then my screen name in English and then more Arabic writing. Who knows.
I'm with Sarah...you just have to be careful what you share online. Never post where you live, where your kids go to school (watch those pictures when you post them...sometimes it's easy to forget that there's a sign in the photo), where you work, etc.
