the way a #Lemmy community just shows up as boosts of all posts and replies to them is just not a great way to represent them here, I believe there are multiple ways this experience could be improved from either side. Already somewhat better with platforms/clients that always show the parent post that is being replied to
in order to post (a reply) to a Lemmy community from #Mastodon (etc.) you need to know you have to mention the community by name which doesn't happen automatically
for a top-level post in to a community there are formatting rules like making the first line of the content the title
Lemmy content discoverability is poor on Mastodon because hashtags aren't really a thing for it
Not all of these have to be fixed to make federation useful and to me it doesn't seem like the biggest issues are insurmountable at all... do you have others in mind or have reasons why these cannot be improved?
