@gicrisf @tshepang @MastodonEngineering I've never been on Twitter so I don't really know how it works there.
The lines do help a little, but nesting more similar to Reddit or other Fediverse software (such as Firefish) is much more ideal I think, as it's even easier to follow conversations then.
I added a small example image from a Firefish reply section to show you what I mean.
