My latest Information Week column is "How Your Creepy Ex-Co-Workers Will Kill Facebook" — in which I explain why Facebook and all the other social networking services live in a boom-and-bust cycle because they get crufted up with people you don't want to add to your friends list, but have to for social reasons.
You'd think that Facebook would be the perfect tool for handling all this. It's not. For every long-lost chum who reaches out to me on Facebook, there's a guy who beat me up on a weekly basis through the whole seventh grade but now wants to be my buddy; or the crazy person who was fun in college but is now kind of sad; or the creepy ex-co-worker who I'd cross the street to avoid but who now wants to know, "Am I your friend?" yes or no, this instant, please.
It's not just Facebook and it's not just me. Every "social networking service" has had this problem and every user I've spoken to has been frustrated by it. I think that's why these services are so volatile: why we're so willing to flee from Friendster and into MySpace's loving arms; from MySpace to Facebook. It's socially awkward to refuse to add someone to your friends list — but removing someone from your friend-list is practically a declaration of war. The least-awkward way to get back to a friends list with nothing but friends on it is to reboot: create a new identity on a new system and send out some invites (of course, chances are at least one of those invites will go to someone who'll groan and wonder why we're dumb enough to think that we're pals).
