The way Lemmy is organised tends to focus users on new and popular content, which means that slower moving ongoing conversations tend to sink in the page and get overlooked. A lot of valuable content is created in those slower discussions, so I am trying to set up ways to keep them visible and findable. I believe for a good group a moderator needs to be part librarian, not just rule enforcer.
I am creating ongoing topic threads which are linked to from the sidebar, and will also be linking them in the daily discussion thread where most activity in my group currently occurs. I am also looking into creating regular posts for specific topic discussions, which should help searchability. Making the system more complicated leads to users not following it though, so I want it to be as simple as possible to use and not have too many things like that happening at one time.
I would love to hear any other suggestions or about things you are doing to set up the structure of your groups.
