Given that many don't have home security, nor fully understand the reach of W3, LBS and electronic data in general, they should know better and remember “Buyer Beware!”. But it all depends to what degree you feel that people need to be protected from their own actions.

It is very easy to overshare online, and forget or be truly unaware of the potential reprecussions of one's actions, as most of us can't infer the progression of technological innovation. It isn't like deciding whether or not to have unprotected sex, where the potential consequences are very well-known to all.

I like my privacy. A lot. I also like having friends, but my friends are all real people, not virtual friends. I have a real life in a real city. I have a real family. I listen to real music. I don't need someone to tell me what I should be interested in. I listen to the same stuff I grew up with and I couldn't be happier. There are very few new artists I find even remotely interesting. No one rocks like AC/DC and no one ever will short of them being cloned.

I use Linux or one of the BSDs, I manage my own domain and email and I keep to myself. I can do a vanity search of myself on Google or any other search engine and come up with absolutely nothing at all. I don't want to be found, emailed, or texted by anyone I'm not already communicating with. I like being anonymous.

It is to the advantage of a business to share the things that will make them more marketable and “liked” by customers. Therefore it is disingenuous for a CEO et all to claim they have nothing to hide and will share all their information. They're only sharing what they want you to know. And so should you!

In terms of the common denominator of user settings, not everyone wants to live like a celebrity or have their 15 minutes. The actions of sites like FB are promoting our society's all pervasive marketing driven cult of celebrity and vacuous drive for people to do anything to gain celebrity and attention via things like reality shows. The internet and FB et all are now one big reality show albiet quite orchestrated by the powers that be for their own benefit. Remember that while a winner of American Idol sacrifices their privacy in a real way for monetary gain like any other celebrity, regular people still have a choice and it can be found in the privacy and account settings on FB and what you choose to share or not or to simply opt out. Caveat Emptor!
