I logged on to FaceBook after being convinced by my Granddaughter...and it still confuses me. But what surprised me was about the 3rd time I logged on, I discovered about 200 people who wanted to be my "Friend" and showed their names and in a lot of cases, their pictures. And I only knew a handfull of them. Some of them were from other addresses I have, and even though I write to them now and then, I've NEVER seen a picture of them before that. Couple of them I've asked them about it and it surprised the heck out of them, knowing that their picture was on an international group. They had sent their pictures to another group of people that have no contact with FaceBook.
There doesn't seem to be much privacy around any more, nor do most younger people seem to even know what the word means.
