Just a working list - feel free to add to it. I realize that some of these might already exist, and I just missed them. Here’s what I’ve got so far:
- Book suggestions
- Obscure Media
- New England
- Massachusetts
- separate communities for every other state too
- Mildly interesting
- Antiwork
- Anti-Amazon
- buy it for life
Probably niche, but /r/skyrimmods. Nexus is a toxic hellhole, but that sub was relatively chill (although had the occasional bit of drama, admittedly).
There is a SkyrimMods community on Lemmy.world.
