If you count only people writing, you are not counting the same thing as "people logged in".
I have data for that for Discord, which is wrong by 50%, due to that many people having disabled metrics on Discord, and can't be exactly tracked, I can calculate this as a ratio of people in the server compared to people in the server reported in insights dashboard. I also regularly prune members, so the inactive accounts don't actually stay around on the server either. On a monthly basis we have about 400 viewers of the channels, and around 30% of that are people that end up writing.
Plus I know of several people that follow the MLs via the archives (I know, because they were confused when we switched to mailman3 and the old archives got no updates anymore), so even number of subscribers gives an incomplete picture.
Subscribers weren't even mentioned though LCP [Sasi] https://lcp.world
