Episode notes
Origin And Revival Of LessWrong
- Eliezer Yudkowsky started LessWrong after blogging on Overcoming Bias and attracting writers like Scott Alexander.
- The site declined around 2015 then Oliver revived LessWrong 2.0 in 2017 as a new forum implementation.
Forum As Durable Intellectual Infrastructure
- LessWrong functions as an intellectual hub that produces high-quality analysis and anticipatory thinking.
- Its archive-style forum produces durable public reasoning that can outperform mainstream sources in niche domains.
Fractal Hotel Layout
- Lighthaven (formerly Rose Garden Inn) is five buildings around a courtyard with a fractal, organically grown layout.
- Oliver describes roughly half the rooms as created by iterative porch-to-room expansions producing unique nooks and non-grid structure.
