I personally judge that quality posts are posts that always benefit others, even though the writing is irregular or the punctuation is wrong, the most important thing is the intent and purpose of the post.
People will understand the purpose/intent of the post if that post is written in the right way. Instead of understanding the purpose, people probably misunderstand if it is written with the wrong punction, unsuitable words, or not constructed properly. So, don't neglect the correct writing procedures since it determines people's understanding of what we write. It will be useless if people can't understand it, people will miss the purpose of the post.
