Hi all, Regarding Marco's point, this is important because it goes back to the 'reciprocity' or whatever you'd like to call it of Facebook, namely that even if I have been extremely careful and guarded about what info I share on Facebook and what I allow it access to, the moment one of my friends has not done the same, and is in some way connected to information of mine (through a post comment, a shared photo, etc. etc.), then the profile is reopened in a sense. The only true privacy is not to be on it, but even that doesn't stop people posting photographs of you on there.

It all started a few years ago when my hairdresser, who I went to once, and who has sent me a few emails, turned up as a FB suggestion. We didn't have any friends in common and I most certainly have NOT allowed FB to go thru my Gmail contacts (or any other account). This all had happened once before when FB suggested another person with whom I sure shared no friends whatsoever. Since I'm dead sure I haven't given Facebook permission to contact my Gmail account and FB sure isn't allowed to mine my cache, I was ready to go paranoid (seemed like Facebook was stealing my Gmail contacts). But after a few emails to friends and nerds of all stripes, we came up with the conclusion that it was the hairdresser who allowed FB to collect *her* contact info. That's how FB knew we had been in contact in a given moment. Bottom line: there are only two ways FB could have gotten that info from me. Either by mining my Chrome cache, and I refuse to consider this possibility, or breaking into Googles's office in Mountain View, since Gmail was the only place where I had that info stored. So getting back to your question, the kid might not know his uncle's e-mail, but my two cent is that the uncle's contact list sure includes the kid's name and/or his e-mail. Either way, this is not good. But it is the future, and the future is here. []s MTB ------------------------------
