One of the letters that I felt was missing in your 5Ws and 1H is an “F”.
F as in formatting, which you do a brilliant job of in your above post.
I have found that Cake’s italics is visually off-putting, and a disruption to ease of reading, if it’s used for more than one sentence in a paragraph.
Sign-post each section with a heading formatted in bold
Long-form posts, which I’d define as anything more than seven paragraphs*, usually benefit from breaking content into sections that are set off with a heading. It also helps to use bold or italics to emphasize a key point to your reader.
Using quotes in your posts, and properly crediting the source with a hyperlink or embedded link, can add credibility and interest to your argument.
Setting off long quotes is helpful, but I think they shouldn’t be longer than a couple paragraphs: the greyed out text can become visually taxing, like italics, if overused. You can also center a profound bit of wisdom, such as this one from 365 Photos Later:
Practice makes perfect.
Use visuals throughout your post to separate sections. Embedded links, which is a link that has been expanded into a clickable image like this
can provide a momentary break from deep reading, which may be needed for readers after they’ve consumed multiple scrolls of content.
*I have no idea where the line is drawn for long-form content, in case you’re wondering how I came up with “seven paragraphs.”
