Same here, VHG. Not sure if I should feel offended or not.
But seriously, Facebook is safe if you have the security settings as high as possible, and it's a great way of keeping in touch with friends and relatives you don't see very often, and if you just don't have the time to sit down and write a letter or email. I use it for sharing family history research with cousins in the US and Australia.
This is a great website about the potential pitfalls of Facebook:
