The “groups” work really well too. Being a young professional, you often are friend requested by people you meet at networking events, etc. on facebook BEFORE linkedin. Sure, I want to keep in touch with these folks and no, i’m not celebrity enough to create a brand page for myself. Somehow I’ve ended up with 800+ friends while i only had ~120 guests at my bar mitzvah (but that was 1995 and I’m much more social now).
As a result, it’s easier to keep non-close friends in the “professional group”. I set it up to have less access to photos, personal info, etc. If we become friends then they can always join my mainstream group which is fully baked.
