It’s quality and quantity. The quality has held despite a drop in users.

This is my experience too; I haven’t really noticed a change. I still see about the same number of conversations and the same depth of conversation as I always have here. I was very surprised that the change in user count was so high.

I wonder if there’s a committed/stable subsection of the userbase, that is mainly responsible for posts and comments, and has largely stuck around throughout? And then most of the swings in user count are from people who were less active to begin with?
