Christoph Lühr's personal blog treats writing as a cache: a stored version of what someone understood, waiting to become outdated.

The site explains its own publishing system in unusually concrete terms: one source becomes both Gemini gemtext and single-file HTML, with no stylesheet, scripts, fonts, analytics, or third-party requests. Its central metaphor is equally sharp—old posts are cached beliefs that can go stale, but remain useful because they can still be read and corrected.

This is one of 1,000 discoveries in the 2026-08-15 Domain Arrivals issue.
