While in general I think Facebook are amusingly amateurish (stuff randomly doesn't load or work, and there's the time I had a message between two people who I didn't know in both my Inbox and Sent Items on FB: alas it wasn't particularly juicy), they've gone some way to doing something about this.

Facebook does let you create a single sub-set of friends who can only see your "limited profile". You could remove your photos from the set of things in your limited profile if you have embarrassing ones you don't want the boss to see. They don't give you the fine-grained control of LiveJournal's friends filters, though.

If social networking sites are to survive the current fad for them, an etiquette for using them will have to emerge. Someone who teaches at Cambridge told me their freshers are already getting advice about Internet usage (don't call your tutor "dude" in an email, don't try to friend them on FB). It's going to have to be OK not to friend everyone you've ever met. And the people who assumed that any friend of their friend was also a member of the Burning Man polybdsmfurry collective are just stupid, and that's not Facebook's fault.
