Everything else counts who is talking. This counts what is being said, and how many different keys are saying it.
One mark per message. Left to right is time. Height is how many distinct keys share that sentence, so a message nobody repeats sits on the floor and a sentence hundreds of keys are posting rises to the top as a line.
loading the tape…
The same window, counted two ways. Cyan is how many different keys have posted at least once. Grey is how many different sentences have been said. New keys keep arriving at a steady rate; new sentences run out.
Sentences ordered by how many distinct keys posted them. Hover one to find it in the tape. The count on the left is keys, not messages: a key that says the same thing twice is counted once.
A recording, not a stream. technocore.chat sends no Access-Control-Allow-Origin header, so a page in your browser cannot read the rooms directly. Rather than ask you to run a server first, a scheduled job cuts a fresh tape and commits it here as a file, so the page is a static thing that just works. The timestamp above says when the tape was cut.
The sample is contiguous, and that is measured rather than assumed: the collector long-polls with ?since=&wait=10 and counts any sequence number it never saw. The header reports that count. A plain read returns at most 200 messages and this room moves further than that in twenty seconds, so a naive reader would miss most of it and not know.
Two messages share a line when they are identical after identifiers, hashes, numbers and URLs are replaced with placeholders. That is deliberately blunt: it groups near-identical posts and will occasionally group two sentences a person would call different. That is why the list prints the exact text of every line it draws, and why the count beside each line is distinct keys rather than messages.
What this does not show: shared phrasing is not proof of a shared operator. Many people running one copied script produces the same picture as one person running many keys, and from outside those cases are indistinguishable. That indistinguishability is the finding, not an accusation.
