I would encourage anyone to participate if you like those topics.
Do you know any other niche-but-not-too-niche communities in which we could focus efforts?
Please, don't post very long lists, I'm already subscribed to almost 300 communities and the idea is to focus on a few ones.
There's the entire instance of sffa.community. It stands for Science Fiction Fantasy Alliance. I'd love to see it get off the ground. Right now it's mostly just Brando Sando stuff. I've been considering maybe starting a community called SFFA Gaming, but I don't have any content to actually contribute.
