Heat counts how many accounts and organisations are discussing the same story: repeat posts from the same one count once, recent discussion weighs more, and weight halves every 24 hours. It shows how lively a discussion is, not how good the coverage is.

The list covers only the last 48 hours. Trends compare the same set of continuously watched sources, so they reflect what we can see, not the whole web; without comparable history no trend line is drawn.

The source list shows only reports that can be read publicly; some accounts and organisations in the discussion are not listed. One organisation posting on several platforms counts once, so there can be fewer participants than sources. Open a story to see each side's reports and views.
