Traction = current votes (PH) / points (HN) — early-adopter attention, not downloads or usage. Gained = traction gained between the two latest daily ingest runs; Gain % only when the previous traction was 5+. Buzz = comments gained in that interval. “frozen” = no longer tracked, so no current gain. How it works
