It's a weird phenomenon, because even those lurkers with accounts who barely contribute might not state how they've not socially benefited from Less Wrong. However, I suspect the majority of people who mostly read Less Wrong, and are passive to insert themselves deeper into the community are the sorts of people who are also less likely to find social benefit from it. I mean, from my own experience, that of my friends, and the others commenting here, they took initiative upon themselves to at least , e.g., attend a meatspace Less Wrong meetup. This is more likely to lead to social benefit than Less Wrong spontaneously improving the lives of more passive users who don't make their presence known. If one is unknown, that person won't make the social connections which will lead to fruition.
