IMO the important thing is removing duplicates and pushing people to post to the most relevant communities (and for us regular users, only upvoting the post in the most relevant community). As well, Lemmy itself needs better means of combining the same post across many communities.
When I say removing duplicates, I also mean for a given event, not a literal duplicate link. We don’t need 5 posts from different media sites on the same event unless a new one is significantly different.
That’s the issue I’ve been noticing a lot. Every major news site wants to post their own opinion piece on how dumb Musk is (can’t blame em) and it feels like every single one of those will get posted to some Lemmy community.
