On reddit, you can’t post basically anything anymore. Go to computerscience, programming, gaming/games… You can’t post ANYTHING. No matter what you post, removed… It sucks. It’s like 1% of people get to post, everyone else is muted…
But lemmy is better. Here, things are fair, there aren’t over-moderation and too many rules. How do we get people here? No one wants to join lemmy.
By and large the posters/commenters for those other communities just haven’t wanted to move over.
It’s just that you need “pioneers”, people who resonate with what’s already here but also want to add to whatever new communities. I don’t think we’ll have a migration of users only for those topics if we first don’t have a few that can already keep things alive as they are.
Pioneers don’t matter for many communities if you can’t engage with others.
