Summary

A short observation on community-size growth failures. Scott's teenage micronation (Shireroth) stayed stuck at ~12 people for 15 years despite recruitment drives and retention programs (which only stretched newcomers' stay from two months to three); the Bay Area rationalist community has the same 'newcomers can't break in' saturation problem. Relays Samo Burja's idea of a cascade of Dunbar numbers (discontinuities around 12, 150, 1000, 90000, tied to family/clan/tribe/city-state, requiring nested subdivision hierarchies to scale past each). Scott is skeptical of the specific numbers but notes the real community-saturation failure mode.

Why this score

Quality 60 · Strong. 60 — Solid/Strong boundary. A genuine, relatable observation (the community-saturation failure mode) with vivid personal illustration, but short, and the cascade theory is Samo's and Scott is skeptical/inconclusive. Firm at the boundary.

Claude’s paradigm shift 44 · Moderate. 44 — Moderate. The cascade-of-Dunbar-numbers idea (Samo's) + the saturation observation is mildly generative.

Real-world impact 1 · Negligible. 1 — negligible. A within-discourse observation; no material reach.
