Episode shape and channel activity
Message volume and episode shape changed together. The tables show episode size, acknowledgement endings and channel activity; they do not establish causes.
Episode shape

|---|---|---|---|---|
| 2016 | 76,145 | 43.8 | 10.1% | 9.7% |
| 2017 | 79,758 | 34.1 | 7.6% | 9% |

| 2026 | 821 | 21.3 | 3.4% | 15.7% |
The recorded duration distribution remains broadly similar: the 30-minute to two-hour band stays around 40%. Episodes became less message-dense : fewer messages occurred over similar durations.

Last activity is the month of the final recorded message in a channel. It does not mean that the channel was deleted.
Final-period activity
For a cohort of 331 members with at least 300 messages, the median final-three-month / preceding-three-month ratio is 0.562 . 42.9 % fell by at least half.
Only cohort aggregates are shown. This describes the final recorded activity of past participants; it does not identify who will leave or establish causality.
