That's a very reasonable and methodic conclusion. The only thing I don't like about it is that if you say it outside of the lemmy space it lacks direction. Someone can say "subreddit" anywhere outside of reddit and anyone will either know what a subreddit is, or be able to find out. Talking about a '[name] forum' the listener might wonder "which forum, where is it?". Even if they know about lemmy.world they might need to ask to be sure that it's the lemmy forum with that name, that is being referred to. In part because many other forums still exist outside of that space.
Thing is, with the naming of the communities there are plenty of cases where saying something like "the [name] community" could easily be misinterpreted. "the linux community", "the android community", "the league of legends community", and so on could either specifically mean the community on lemmy.worlds, or just the general community/fan base of something. In a case where something is only meant to specifically refer to the community on lemmy.worlds, a distinct word would be pretty helpful to make that clear and leave no room for misinterpretation.
Heh. I wouldn't mind either of those ideas, they both sound pretty alright to me.
Arguing from that perspective that would make a lot of sense, yeah. My chain of thought was going more from the sound and what people might want to 'naturally' call them.
The android version of Dicey Dungeons plays very well. I can definitely recommend that one.
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.
