Highlighting on Medium is amazingly annoying. I love that people respond to my poems, but I hate the mess that highlighting makes. In other words, I completely agree with you. Apparently I can't do anything about it, even though it ends up looking like a real mess. Apart from the appearance, I don't want a new reader to be influenced by the messy tracks of other people. I want them to find their own highlights and explore a virgin page. I certainly don't want them to think (even subconsciously) "oh, there's a good bit coming up", or "why did that person highlight that bit in particular?" I think this maybe especially annoying for poets. A solution may be to highlight the whole damn thing myself, but that seems a bit unnecessary. Do other poets care about this?
