Hacker News Comment Review
The only substantive comment zeroes in on methodology credibility: publishing losses builds reader trust and is one of the few content types that survives AI-summary commoditization of niche aggregators.
The commenter raises a sharp practical question about methodology drift: quiet nudges over time vs. versioned, dated updates are very different things, and the distinction matters for backtesting integrity.
Notable Comments
@mbtrilla: “how often do you actually update the methodology vs quietly nudge it” – flags that versioning discipline is the real test of transparency, not just publishing a methodology page.
