Ok so you want to develop some "high quality" social network then. Why not just create one on Ning? Ning allows you to create your own social network. And so what if you create this "high quality" social network. What is the added-value that someone cannot get through personal messaging, forums, e-mail, and current social networks. You also talked about integrating your own identity. How is this different than MyspaceID, Facebook Connect, Google Friend Connect, and Open ID? These services allow you to be interconnected so that your reputation and presence among other social networks is constant. Lastly, I believe we're going to see a transformation of social networks. I agree with that part of your initial statement. But this transformation will arise from a gap in a practical need. You have not fully convinced me that there is a gap. So just to give you some brief, unsolicited advice, I would say that you should look for problems that you encounter in your daily life, and create some tool to fix them. If its important enough, then your userbase will follow. I would also research all the different types of social networks and how they currently function, especially from a technical point of view. You tend to throw a lot of technical jargon around. I want to give you the benefit of the doubt, but you have to be clear about your terminology. For example, when you mention "signal-to-noise" ratio, I think gaussian noise and signal processing. :)
