Even if I knew what the conversations were about, it would still make my main feed extremely noisy. Replies don’t show up in the main feed (in Damus) which make the main feed manageable. When every reply appears as a top level note, it gets too noisy. That’s one problem with having no algo for the main feed.

Ah, I misunderstood what you were trying to do. In that case, I suppose lists is an option (though I'm most sure it's available on Damus yet, on Amethyst you can see home TL basis regular follows or specific lists).
The nature of Japanese TL is that it's a lot of posts, so can't change that 😅
