Basically how reddit would call any given reddit sub-community “sub reddit” or just “sub” for short. I know internally lemmy just calls them ‘community’ but in a regular conversation ‘community’ might be interpreted as more broad or too general.
Thinking about it my mind would pretty much automatically go to ‘sub lemmy’, but then I felt like just shortening it to ‘blemmy’ has a great ring to it, while still being distinct. So if there isn’t already an established name, I’ll go ahead and propose ‘blemmy’.
I like community, makes more sense than sub really. Maybe call it a com for short?
What I like about ‘subreddit’ is that it’s still very specific when you use it outside of reddit. On reddit you can easily just say ‘sub’, whereas outside of reddit you’d say ‘subreddit’ to make it very clear, what specific place you’re talking about. If I say ‘[name] community’ outside of lemmy, even someone who uses lemmy wouldn’t necessarily know I’m specifically talking about the lemmy community, unless the context already made that very clear. And that distinction can be helpful in a conversation.
Or dom, the opposite of sub.
