You'd have a hard time getting people to use it, because I've found that the majority of people dislike change. Adults particularly that have become accustomed to Facebook are not going to use a beta quality social network that doesn't work like Facebook did. Because of that difficulty to bootstrap the community, people will have less of a reason to use it. For me, I care more about being able to communicate with friends and family much more than I do the privacy of the things I'm uploading.
