I think a lot of folks here on Slashdot are a little paranoid about privacy... Or, at least try to sound like they're paranoid about privacy.
The fact of the matter is that there's precious little privacy in the world. When I'm working out in my front yard, I've got no privacy. When I'm shopping or driving or walking down the street, I've got no privacy. At work I've got no privacy.
Why would anyone expect that posting something on the Internet, quite possibly the most public space in the world, would be private?
Your analogy is seriously flawed. When you are out working in your front yard, shopping, driving, or walking down the street, you do have privacy. Unless of course you walk around handing out cards to every single person you pass that includes your full name, city, country, gender, picture, a list of all clubs/networks, a list of all your friends and their associated full names, cities, countries, genders, pictures, clubs/networks, etc.... I personally don't have such a card much less pass it out to every person I ever see.
As an audiophile myself, I too wondered about this.
