I've heard it a few times recently, then saw something posted in i think the autism instance? Dunno, not sure which it was, but this popped into my head and thought it illustrated it neatly.
Community and Instance actually have a hard meaning here. Communities are the equivalent of subreddits, while instances are the equivalent of reddits. Reddit only had the one instance of course.
I wonder if mastodon has communities. Or is there a more twitter thing they do?
I think mastodon is more akin to Twitter, but I can’t really say as I haven’t used it. Thanks for that clarification though, it is a pretty important distinction.
