I like this approach of thinking adversarial about it. I’d done the same before signing up for my (eponymous) account here, but arrived at a different conclusion. Completely agree with all of your logic about combining public information to find private information.
I think my conclusion was different as 1) LessWrong is quite focused on long-term stuff, and while my interests or style change as time goes on, my name won’t so this future-proofs it; 2) I don’t expect to post anything particularly controversial (and could also make another account to do so as needed); and 3) I have a pretty common name (although I’d bet that if you searched my name on LinkedIn and played a game of “who would be most likely to be on LessWrong based on their jobs/interest/education”, your odds of picking me would be high :)
Curious to hear how others thought about the username thing?
Great post, absolutely agree with the value of this approach.
Wanted to add a productive question with a social angle: Who would you not want to have a serious conversation with about your life? What part of your life would you not want them poking at, and why?
My guess is that many people avoid conversations with people who they know will confront them on issues they don’t want to face. And I wonder if we can use this to our advantage by asking the question above.
If anyone tries and feels comfortable doing so, please report. I’ll try myself too.
