Anybody who wastes any time at all on facebook should certainly get the Unfriend Finder app. It is a thing of beauty: tells you who has unfriended you lately.
Maybe it’s perverse of me, but I think the history of unfriendings is a lot more interesting than the history of friendings. I don’t have many facebook friends, so I have a correspondingly small number of unfriends. But I treasure the ones I do have, and they are all big rah-rah’ers for Obie and the Dronocrats — the sort of people who are always posting little clips from some TV humorist, Bill Colbert or Steven Maher or somebody.
The only defect with Unfriend Finder is that it doesn’t tell you when, exactly, your new unfriends clicked you into Sheol. I would dearly love to figure out what sent each of ’em over the edge.
