Side note: do people really use "sign up with <...>" buttons? I can't imagine agreeing to let facebook snoop on my browsing habits outside their site, or let twitter tweet on my behalf.
In what way would you predict that allowing facebook to snoop your browsing habit will have an impact on your life?
I can't speak for shminux, but for me (weighted possible future effects of more surveillance) + (visceral disappeal of facebook in general and it recording my activities specifically) would be significantly greater than (a few additional seconds of inconvenience)
[Some of this might be rationalization, especially the visceral distaste. I was about to add a term for the possibility of my behavior being broadcast to my acquaintances in some manner, but I realized I had thought of that after making my decision.]
In late December 2013, Jonah, my collaborator at Cognito Mentoring, announced the service on LessWrong. Information about the service was also circulated in other venues with high concentrations of gifted and intellectually curious people. Since then, we're received ~70 emails asking for mentoring from learners across all ages, plus a few parents. At least 40 of our advisees heard of us through LessWrong, and the number is probably around 50. Of the 23 who responded to our advisee satisfaction survey, 16 filled in information on where they'd heard of us, and 14 of those 16 had heard of us from LessWrong. The vast majority of student advisees with whom we had substantive interactions, and the ones we felt we were able to help the most, came from LessWrong (we got some parents through the Davidson Forum post, but that's a very different sort of advising).
In this post, I discuss some common themes that emerged from our interaction with these advisees. Obviously, this isn't a comprehensive picture of the LessWrong community the way that Yvain's 2013 survey results were.
My overall takeaway is that LessWrong seems to still be one of the foremost places that smart and curious young people interested in epistemic rationality visit. I'm not sure of the exact reason, though HPMOR probably gets a significant fraction of the credit. As long as things stay this way, LessWrong remains a great way to influence a subset of the young population today that's likely to be disproportionately represented among the decision-makers a few years down the line.
It's not clear to me why they don't participate more actively on LessWrong. Maybe no special reasons are needed: the ratio of lurkers to posters is huge for most Internet fora. Maybe the people who contacted us were relatively young and still didn't have an Internet presence, or were being careful about building one. On the other hand, maybe there is something about the comments culture that dissuades people from participating (this need not be a bad feature per se: one reason people may refrain from participating is that comments are held to a high bar and this keeps people from offering off-the-cuff comments). That said, if people could somehow participate more, LessWrong could transform itself into an interactive forum for smart and curious people that's head and shoulders above all the others.
PS: We've now made our information wiki publicly accessible. It's still in beta and a lot of content is incomplete and there are links to as-yet-uncreated pages all over the place. But we think it might still be interesting to the LessWrong audience.
