Wow you covered a lot of ground here. I am one of those people that lives a pretty open life online (my profile name here is real first / middle initial / last name for isntance) and just kind of assumes that everything I put out there on the internet, or say in an email, or do online in general, is just kind of public knowledge. Like if I don't want someone else to know about, I won't do it online, or with my cellphone LOL
But I think you have some good info for people who don't want to live with this degree of transparency. Following you - great post :)
Thanks
