As of late I have been unfriending several folks because of political BS. I have it for MC related stuff and a few "real" friends, not virtual friends. When I get a friend request I simply look at their page, view a sampling of their posts and decide if I want to accept their request. Heck, I un friended my son, he was one of those who shared every little bit of idiotic stupid, stereotypical things that just tick me off. FB is what you make of it, it isnt about the number of friends, it is about the content of the friends (virtual) you have, and the contents you provide. No different than any other forum, with the exception you are the moderator of your created forum.
