One more thing, I feel that if SN were to be taken seriously, it has to broaden its scope besides Bitcoin.
I think I saw in a presentation once that the SN business model is: we're building a platform that supports certain features of media and community and takes full advantage of btc and its ecosystem to deliver them; and its original focus will be btc bc of the natural fit in doing that; but it's not really dependent on btc as a topic.
(I think that's pretty close to what I saw but I don't have time to dig for it now.)
Point is, I don't think SN gets bigger or more relevant (or profitable) by more than a constant factor when you have to care about btc to be here. I have a fundamental assumption that, just as you don't have to be a car enthusiast to want to drive to the grocery store, a very small number of people in the world will ever want Saifedean Ammous's face tatooed on the small of their back. That market is tapped out already.
Either btc is money, plain and simple, or it isn't, and if it isn't, this is all going away, and it's only a matter of time.
