But the problem with giving your private information is that if at some point someone makes bad use of it you have no way to turn back and say “I don’t agree with this use of my information.” At that point you might even have to move to a new address, change your phone number or even, as Eric Schmidt suggested, change your name ( http://www.telegraph.co.uk/technology/google/7951269/Young-will-have-to-change-names-to-escape-cyber-past-warns-Googles-Eric-Schmidt.html ).

As a person who shares a lot of information here on this blog, I might be a good candidate for a future name change. And that makes me worry.

The old days are gone.
If you change your address or phone number, you don’t need to send an email to everyone with the new details and consequently every friend needs to update your details on his address book.
With the new approach, his address book will be updated automatically with your new phone number when you update yours.

I agree that facebook is not really concerned with privacy and they’re checking the bouderies all the time, and it’s good that you published this. Facebook listened to you and others protesting.

But still, not give any information is like banning them.

I’m also concerned with privacy, but thought of just seeing if giving my private details ricochets. Nothing so far…

I had my contact info removed and disabled all Facebook applications a long time ago. I’m glad I did.
