Jonah has one:
Is it bad form to “un-friend” folks I don’t know personally and send them to the fan page? It seems awfully rude. But I have actual longtime 3-Dimensional friends who can’t “friend” me because I hit the limit.
I don’t have that problem, not just because I’m not as popular and well-known (and debonair) as Jonah, but because I take Facebook friending almost (but not quite) as seriously as meatspace friending. I don’t Facebook friend people that I don’t know and have not interacted with (at least on line, if not in flesh and blood)– to do so would seem to make the term “friend” meaningless. The only exceptions are if we have a high number of mutual friends, or if someone takes the trouble to write a note with the friend request explaining who they are and why they want to be friends, which doesn’t happen very much (about three times, in my experience).
That said, it wouldn’t have to be rude if you explained why. I would think that most would understand. It might be nice to have a script that would be autogenerated when you did it to provide the explanation. It would be a pain to have to cut and paste it for each unfriending. And never having unfriended someone, I’m not even sure that such an explanation is an option, short of actually sending them a Facebook message, which would be a royal PITA. I don’t think you’re automatically alerted if you’re unfriended (it’s happened to me once, and I didn’t receive any notice of it — I just noticed one day that they were no longer my Facebook friend, or rather, I wasn’t theirs). So I guess if you unfriend a lot of people, some of them will notice, and some of those will ask for an explanation. I guess something else to do would be to put up a notice on your wall warning the general Facebook friendom that some of them were about to become unfriended, with an explanation why and a request not to take it personally.
