This is probably the wrong place for this, but is there any intention to have something like super communities, where the same community exists on multiple instances but is treated like just one?
Ie, if you sub to asklemmy on world, you see content from whatever other servers have asklemmy.
Some Lemmy clients let you group communities. Depending on what communities you group together, it’s kind of like that. But like @dual_sport_dork@lemmy.world said, it sounds good on paper but the logistics become crazy once you factor in things like moderation and culture clashes.
Yeah the real answer is “Yes its possible, but only client side”. Making a web interface that allows grouping together different communities and their posts into one “meta community”. That way the origin and moderation of posts doesnt change.
You could even go as far as creating importable community groups curated by individuals like a playlist of sorts. If you like or dislike something you can add or remove it from those groups. Responsibility for what you group together lies entirely with the user and reports for individual posts and blocklists would apply just the same as usual.
