I think there's another big one too: Option 3 is for very personal stuff that you don't want to make public. Many of us put photos of our small children in this category. On a more depressing note, this could also include things like grief that a small group experiences over serious illness or death in the family. Not everything non-public is necessarily risque. (FWIW I'm working on something in this space. Hoping to have something to share within another month or two...)
