Can an AI answer engine retrieve this page and lift a usable answer out of it?
Can a machine get this page cleanly, quickly, and on the first try?

This reading is close to a controlled experiment. Hacker News deliberately does almost nothing the thermometer rewards: no meta description, minimal markup, no structured data, no Open Graph. It is enormously visible anyway, on the strength of exactly one thing this instrument cannot see.
