I agree that the public/private/partially-shared features aren't terribly effective and as such am careful about what I post. I do however find them useful. I don't allows re-sharing of my photos and I've told everyone I share photos with that I don't want them re-shared, specifically on facebook. Anyone that goes to the effort to download and share my photos clearly doesn't respect my intent or concerns and is removed from the list of people I share with.
