Oh, wow, that must be brand new. Yeah, if someone is setting up a pathfinder focused instance with granular sub-communities that are well moderated, that could very easily overtake this community as the most popular pathfinder space.
I wouldn’t worry about posting here (or other lemmy.ml communities) overwhelming the server. I’ve seen recent posts where the admins say posts/comments aren’t the problem, it’s users joining too fast and browsing too much. So this is still a fine place to chat PF2e… though I’m definitely gonna go check out pathfinder.social and hopefully it takes off. This has not been very active.
