I discovered Lemmy via links from Mastodon, and so found i prefer these threaded communities. Nevertheless individual “status” posts have a purpose too, we need both topic-focused and people-focused structures, these should overlap and connect better.
As my Mastodon account follows my Lemmy account, my posts/replies get into that system, more might be discovered if I included hashtags here. However I can’t do the reverse - follow a Mastodon account, or reply to or boost a post, from Lemmy. Communities might grow more if we could enable such interaction.
