In this case it's like if there were centuries of already written code with huge value, all written without comments. You don't want to limit the ability of programmers to read it. However things are very different in their dynamics: reading text without well separated paragraphs is mostly a matter of habit: a simple skill to achieve, so discouraging this ability has very little return. Lack of comments make reading code a lot harder in certain cases, especially since many informations in the comments are non local.

Also I'm not against proper formatting of posts. Just if it's not separated in paragraphs readers should so the small effort of doing it mentally, instead of complaining. Similarly I'm not against code comments (but strongly in favour).

Btw I replied for the sake of argumenting but the two things are not comparable. Just so this test: splitting text written by others in paragraphs is a very easy task you can do just reading the text one time. Commiting code you don't yet understand is impossible: many informations you should write are not implicitly in the code. It's the contrary actually: most good comments are about things that are not evident.
