It’s not just lemmy that’s benefiting from Elon Musk.
I found fishing for (and following) hashtags on Mastodon effective but Mastodon was also in much better shape to receive the waves of Twitter exoduses.
Lemmy lacks effective tools to organize a feed. I think many people recreated their favorite subreddits as communities but the userbase was too small to support them. Being able to create “multi-reddits” to group related micro-communities together to help mitigate the ghost town feeling as you raise the probably of at least one of them having something new to talk about.
Re-reading your post before I hit submit… I think I am just repeating what you are saying!
What I was saying:
I think the solution is “meta instances” or “meta communities” or “meta aggregators”.
A community or instance that aggregates the smaller communities.
And some way for smaller communities to submit content to that aggregator.
Like, I’m browsing my instance’s “all”. I find a good meme that suits my “programming memes” interest. So, I submit that post to the aggregator.
Essentially like cross posting, but a community of all crossposts and everything is treated like it’s on the original instance.
But as a primary feature. Where it’s easy to “submit to aggregate subscription” or whatever.
But then we would get every instance with their own meta-community, and it’s just a complication on top of communities and instances.
