@colinwalker I have done the same thing in the past as well. While I was formatting my writing with Markdown, what I was writing was never going to be published. There wasn't a need for me to apply formatting from a presentation perspective, it's just that I wanted to emphasise certain lines and paragraphs as a revision aid.
For myself I don't see it as thinking about formatting for publishing, but more for formatting to make it clearer for myself when I come to read it again.
Use what works for yourself.
@colinwalker I’ve realized that we do two basic forms of writing - one where we’re writing something personal, or something new - something where the surroundings don’t matter. But the other form is when we’re discussing an idea, always in relation to someone or something else. In that writing, we tend to want to quote those ideas and people. Neither one is the lesser form of writing, and if you do write the way you do, it’s because you write the latter form more.
I think that’s perfectly fine and you may be overthinking it... 😊
