Fixing grammar could be annoying for sure (like you have nothing better to do, I worked with non-native speakers for 10+ years now and still find it astounding when some native speaker feels the urge to fix someone's grammar in online forums, which I would never do if the content is comprehensible), but adding paragraphs to unreadable block of text can't be even annoying, that's just common sense and everyone can agree Reddit/HN formatting is mess
I agree that we need to keep the HN as simple as possible but it is quite difficult for me to find a way to break lines although i am a software developer in the past. This is an issue for sure.
