There was some discussion about it in Dessalines's recent post. The reason I think it might be visually overwhelming is because of long titles and because sometimes there are a dozen crossposts. Maybe something like Photon's crossposts display can be combined with the other idea of showing comments from crossposts, two birds one stone kind of thing.

I'm just gonna copy a comment I made on Dessalines's post:

Combine posts and not just comments.

In addition to my other suggestions I think showing crossposts with their own comments would be very easy to understand and no one would miss the context because the title and body text of each post would be there. Basically add a section at the end that says "Crossposts" and have a little 🛈 or � next to it that explains the whole thing, when you click on "Crossposts" it expands and shows post previews like when you're browsing (with the + sign to see body text) and the comments appear below the preview. And this could be off by default so it wouldn't confuse new users.

This is just feedback, I do appreciate your work, and I know implementing ideas is not always easy.
