Yeah, the idea of what I might be asking for is somewhat inchoate. I think I'm still shocked at Wikipedia getting a lot of outside feedback at all - actually becoming famous, then going beyond that to an assumed part of life. What? How on earth?

To bring it back to on-topicality, where is LessWrong now? It's gaining participants slowly. What's the aim? "Refine the art of human rationality." How would that scale if readership doubled tomorrow? What would happen if LW got famous? How could that occur? What function would the site have?
