I have found that the word, 'friend' means NOTHING on Face Book. These people are NOT friends...many of them are screaming SEE ME.
A good example is what duffsmom wrote below. I have the same problem she does, but I don't dare 'unfriend' that person because the individual is a relative, and I don't want to hurt her/him. This person is very addicted to FB, and does the same thing as the person duffsmom unfriended..."walking into Boscov's' etc, etc.
That being said, my sister has been 'unfriended' by a couple people and she was very hurt.
I visit Face Book about twice a week to respond to any notifications, but that is it.
FB is like anything else. It has its positives and negatives. I was able to track down a long lost friend, so that was a good thing. But it is not my obsession. I would rather visit Hub Pages, as we all share a common bond: we love to write.
Blessings, Sparklea ;)
