Experimental: traction = early-adopter votes (PH) / points (HN), not downloads or usage; updated about once a day and frozen ~31–36h after launch on Product Hunt (7 days on Show HN); sectors come from keyword rules (~70–75% accurate); data starts Oct 3 (HN) / Oct 9 (PH). “—” means not enough data; nothing is estimated.
