Heat comes from independent accounts and organisations taking part in the same event; repeated 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 ranking covers the past 48 hours. The trend only compares the same set of continuously covered sources; it reflects our monitoring range, not the whole web. Without comparable history, no trend line is shown.

The source list only shows publicly readable reports; discussion participants also include accounts and organisations that only count toward heat. Several channels of one organisation may be counted together, so participants are not always more than sources. Select an event to see each side's reports and views.
