Signals are linked to their original public sources. Activity and decay are shown only where repeated observations support them.
Detect. Track. Analyze. Act.
FWA uses repeated public-source observations to show measured activity. The activity change compares the last two valid observed intervals, normalized to points per hour. The experimental pattern label compares the latest four consecutive HN score-rate intervals (at least 75 minutes). Sustained means 3 of 4 intervals remain near the observed peak; Post-burst means a distinct spike followed by a sharp decline. Mixed means neither rule is met. This is not a measure of comment bursts or a prediction. A state can reflect the observed peak, so state and latest change may differ. When data is insufficient, the index shows “Insufficient data” instead of a guessed percentage. Bookmark and share signals yourself; FWA never auto-posts.
