I know, for me, i clear out my 'friends' list whenever i think it's bloated by people who have disappeared, rarely come on or that i have nothing to do with. A large friends list means nothing to me. It doesn't prove anything about who you are, it only proves you have a large number of people willing to accept your invite. Which means nothing because i get invites from people i've never seen before. Unless these people were close friends who suddenly and without warning abandoned you then who cares?
