Your idea doesn't sound particularly tenable. A pay social network that limits you to only your close friends and family, that will have no network effects, have less features, and be more difficult to set up...
It's easy for people to point what they don't like about Facebook, but I don't think you are really comprehending why they dominated the social network space to begin with. It's not as easy as making a product that doesn't advertise, if it costs money to use instead.
Tenable for what? You are injecting your own ideas. Why would I care about the reasons Facebook is popular. The idea I submitted was to make the process of setting up overlay networks easier, not to try to start a web-based business. Making software easier to use is a tenable idea. The ideas you are introducing might not be tenable. However, they are not my ideas. The pattern I see is you introduce some idea, attribute it to me, then shoot it down.
