Ah, see, you didn’t recreate it just because of the interface; you recreated because it’s currently a high-trust social environment, because your friends and family are using it, because they know who you are. Old Facebook was high-trust because we all were naive and trusting.
Perhaps the question is how to continue to create high-trust environments from a social perspective, not an interface perspective.
