It should be rather simple to add an (optional?) article-view which roll's up a chain of comments from the same author, and presents it as a flat collected text. Each comment would a single paragraph, showing if there are comments from others, to this specific paragraph, which could be shown as an overlay, inline or on the side. No functionality would be lost, but it would improve readability significant. I don't understand why twitter and similar services, never made an attempt to improve their chaotic system. I mean on Twitter there are even bots doing this on external websites.
Once it started becoming common to start attaching screenshots of text to Tweets (many years ago now), I wondered why they didn't think to allow add "text attachments" similar to how images and videos are attachments. You put a description of the post within the normal text limitations, and tap a thumbnail to load a long (maybe even markdown-formatted) text and read it. It keeps the feeds short both visually and in bytes.
It's the same as long Twitter posts, strung together by endless tweets a few years ago. People have a platform, they use that. If you don't make it a habit to post long articles, why bother with a new platform when the one you have will suffice?
Making a substack, or an account on Medium is "yet another thing" and many simply cannot be bothered and I don't blame them.
or at least better compatibility with reader view... it would just make sense. i was about to suggest it when it worked with brave's one (xtwitter articles and bluesky threads didn't), but then it didn't work in safari
