Heat comes from the independent accounts and institutions taking part in an event; repeat collection counts once, and it decays with a 24-hour half-life. It measures how active the discussion is, not the quality of the reporting.

The list covers the last 48 hours. Trends compare only sources covered continuously; they reflect what we monitor, not the whole internet. Without comparable history, no trend line is shown.

The source list shows only sources with publicly readable reports; participants also include accounts and institutions counted only for heat. Several channels of one institution may count once, so participants are not always more than sources. Open an event to see every side's reports and views.
