Nice post, @kll. This version of the forum has been running since May 2018.
Some other facts from the mod stats board:
One the one hand, the forum gets ~10 new signups and ~5 new contributors (first post) every day – some of these users will only ever create a single thread, e.g. a student working on a term project. There are about 20-40 daily “engaged users” (who are posting or liking things). ~30-80 new posts a day in ~5-15 new topics. It is a small but healthy community, and even most active accounts are lurking readers – each day about 600-800 logged-in users visit.
Most forum users, however, are readers who never create an account at all. When the new forum opened, it started at around 20,000 page views per week, and has grown over the last year and a half to 40-50,000 page views per week – although some of that could be web crawling, of course. Still, it is as much an answer board as a discussion board, and high quality answers can help people for years.
The forum is also seasonal, and activity is tied to the school year. Spring is usually busiest, Summer and early Fall is usually quietest.
