I also just joined in the past month. You're welcome
I did because I was on a different Fediverse link-aggregating forum that was pretty quiet and getting quieter, and all the communities and threads I saw over there came from this instance. It just made sense to join directly so I could post and get proper notifications.
The supernova from Rexxit sent a lot of small pieces flying out everywhere, but things will start to aggregate back down to a few winners over time. I went to Squabbles, Kbin.social, and then Discuit... but now I'm just here and Discuit. I like Discuit's look and feel and users, but it's not super active.
