How do we deal with similar communities on different Lemmy instances? - Lemmy

Say what you will about reddit, at least an established subreddit was the place to gather on the topic, ie r/technology etc. With Lemmy, doesn’t it follow that similar communities on different instances will simply dilute the userbase, for example [email protected] and [email protected]. How do we best use lemmy as a (small c) community when a topic can be split amongst many (large C) Communities? This is an earnest question, in no way am I suggesting lemmy is inferior to reddit. I’m quite enjoying myself here.

It would be really nice if communities could be connected right at instance level.

So if you have c/abc on instance 1 and c/abc on instance 2, and you subscribe to either of them, it would, by default, subscribe you to both (assuming that both instances agree to such a cooperation).

Something could also be arranged within communities, especially when it comes to posting. Such as, when posting, to be able to select multiple coms to post to, but it would still be just one post you could edit or delete, and have all the comments in one place.

For subscriptions, I would personally favor a "discovery" mode. When you sub c/abc on Instance 1, it tells you about c/abc on Instances 2 and 3 with the option to sub to them individually.

I like the idea of a single post that gets tagged to the communities it should appear in. Moderators would probably want the option to block or control something like that though, considering the risk of spam.

I think this would reduce spam if anything. If someone does misuse it, then only one post needs to be reported as spam instead of every sub/com needing to deal with it individually.

Also, a user who is subbed to multiple coms, would only see the post once instead of multiple times.

And for actual spammers it's never a problem to make a hundred identical posts anyway.
