I think a large portion of lemmy is too focused on making lemmy popular. Fake engagement and posts that nobody cares about don’t create engagement. Instead, more focus on just enjoying lemmy would ironically lead to better posts and discussion. Likewise, people post the same articles to the same communities seeking engagement. It leads to dupilication which waters down the discussion, ironically, also leading to less engagement. I think federalised communities, as has been discussed would be a good solution. However, it strikes me that they don’t want to miss out on karma, for some reason. So, short term gain, for long term hassle of multiple posts. If some of the most prolific posters posted to the most relevant community and cross posted elsewhere, then maybe communities would coalesce more.
