Small-Scale Question Sunday for July 12, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I am somebody who is very much intrigued by 00s vBulletin forums and 90s Usenet newsgroups. I know that the rationalist movement was pioneered by Robin Hanson with the Overcoming Blog and Yudkowsky's Sequences around 2006. Where did the proto-rationalists hang out prior to that?

The immediate precursor to Overcoming Bias was the Shock Level 4 mailing list, and the precursor to that was the Extropians mailing list. Eliezer met Robin on Extropians; he is cited in Hanson's 1999 "Comments on Vinge's Singularity" page.

For those of you that don't know what a mailing list is, it's basically the ancient equivalent of a subreddit; e-mails sent to the group's address would be forwarded to all subscribers. I'm not old enough to have ever used one; I cut my teeth on internet forums similar to Data Secrets Lox.

I remember spending a lot of time in the orbit of Eric S. Raymond (ESR).

ESR traces a lot of pre- and proto-rationalist influences here, but they're mostly works rather than communities: https://www.lesswrong.com/posts/qc7P2NwfxQMC3hdgm/rationalism-before-the-sequences

https://www.lesswrong.com/w/history-of-less-wrong covers the pre-2016 history, including the SL4 mailing list.
