You know that giddy feeling you get when you think you've struck it gold with a genius idea only for that excitement to settle after you've given it a bit more thought? Yeah, well, it's that same feeling people get when they tag all their friends in a bunch of photos, or post something inappropriately on someone's wall; and once it is up in the public's eye, they feel it'd look cowardly of them to retract whatever statement they might've made. So with a feature like that, you're essentially stalling the entire posting process and increasing the chance of people engaging their filters to assess whether a specific post would be appropriate for their world to see. If I know that the pictures I just uploaded won't all be up for everyone to see instantaneously, and that so-and-so will have a chance to filter through the pictures before they're posted, I'd likely not be as excited about posting stuff and I'd actually start posting less. You're basically putting a kink in the hose.
If you've noticed, after all the privacy features Facebook has implemented, not one of them involves moderating the brain -> screen process. I may be reading too much into this all, but I do have a feeling that Facebook understands social dynamics and pressures extremely well and places its users in positions where they will almost always choose the decision to benefit Facebook. For instance, you want to be 'friends' with both acquaintances and friends, and so both groups have the ability to post on your wall. You could block those who you feel may say inappropriate things, but that is a burden and they'll likely find out. So what's your next option? Not allowing anyone to post on your wall. But then you'll seem cold and unsocial. So you'll likely choose to keep your wall open for posts.
People tend to hate on Facebook, but I think they are psychological masterminds.
