I've found I spend too much time on caveats and 'sidebars', which slows down my writing; the resulting text also gets too meandering and hard to follow, so I'll spend even longer trying to improve it; then it gets too dense; and so on. The article's advice seems useful, so I may apply some of it to my growing mountain of 'unfinished' posts. One thing I like to do is add HTML <details> elements for caveats or interesting tangents; these don't break up the main flow too much, their contents can be written pretty much separately from the main post, and they can be added/amended later if desired (e.g. if we find out something new and want to update an old post)
