I think that a lot of markdown editors also understand HTML, so you can mix and match (and in some cases, you have to, as there’s no MD standard for underline). But I get what you’re saying - it is definitely a learned skill, just like any other formatting language.
Good luck with learning it! Eventually, I think, it will click for you one day and you’ll just use it subconsciously even in editors that don’t support markdown.
I think MD is what we would have had as the standard had Microsoft Word never come along with it’s bold, italics, and underline buttons and hotkeys.
That’s what happened with me. I use Obsidian and Zettlr daily for writing, planning & note-taking, and it definitely just sinks in — something about seeing the results rendered immediately, I think. Now, Markdown’s minimalism just really works for my brain.
My mail server goal isn’t to have something welcomed by the world, but to give me a quiet hole for the “never used” backup email address.
I currently have public facing on Gmail and less public facing on Tuta, but both are out of my hands. Having an email of last resort seems like a good backup plan, but the setup seems to be intentionally obtuse.
