On the other hand

Nick Douglas complains at Valleywag:

Remember when all you had to worry about on Facebook was some awkward acquaintance adding you on Facebook too soon? (You know, like they talked to you at lunch once and instantly wanted to be your friend?) Maybe sometimes you got invited to the “Two and a Half Men is TV’s Greatest Show” group? But now I’m getting bombarded with crap like “Jim-bob wants to share movies with you” and “Janiqua wants to share secrets.” No, I don’t want “free gifts.” No, I don’t want to be a zombie. No, iDon’tLike. So stop spamming me every time you get an app. (Unless it’s that rocking graffiti wall.)

Right. Letting the world in won’t ruin Facebook (because we still see only a small part of that world). Opening up Facebook to apps will only help it. But apps that spam us? Stop! Please! If I told you once, I told you a hundred times, I don’t want to share bookshelves with you.
