Thank you for visiting!
A post's quality is always the key; the formatting can only make it more appealing and easy to read.
The formatting also depends on the character and style of the author, as well as on its topic. Posting an image with a story might not require all the above.
However, you are absolutely right that it is a universal writing method and structure should be always considered, especially when writing scientific articles! I am happy to get to know more people like you or @indigoocean on steemit that I can use as an example :)
