HN wrote its unwritten rule down: no AI-generated comments. If you reply to buying signals there, the bar for sounding human just got official.

Original data from 975 Ask HN posts and 20 subreddits: median time to first reply on a buying-intent post was 16 minutes, 92 percent were answered inside an hour, and every intent post on Reddit came from an operator community, none from a builder one.

Ninety days of Shadow Inbox data: signal volume per platform, niche intent density, conversion funnel from signal to call, and the surprises we didn't expect.

HackerNews monitoring with the Algolia API, a cron, and an optional LLM filter. The full setup costs nothing and replaces the $5K SDR tool you almost bought.

HN's Who's Hiring thread is a buying-signal goldmine. Full workflow: scrape, parse stack, identify fit, send a 3-line cold email referencing the JD.

HackerNews comments hold richer buying intent than the front page. The 4 comment patterns that signal active evaluation, and how to engage without getting flamed.
