While I agree there are better formats than markdown, I don't even care anymore lol. For me, I have achieved the dream of writing text files any way I wish (as long as it's markdown format loll), in terms of I can do it in a text editor, obsidian, zettlr, who cares. Beautiful! Next, I can have webpages created instantly as I modify. To me, this setup is basically future-proof, and now I'm just creating content.
Also, I am pleased to say I am maturing in my use of the whole zettelkestan method. THe last couple of years, I've been trying to "follow the rules" and so forth while I learn and adopt it. But now I see it doesn't matter what the rules are, but the ideas are good. I got into a habit of making fairly long notes, as once I start writing I just go. But now I see the value of having short, concise rules as going back to read or use the notes is not very productive when they are long. So now I'm in the phase of shortening the longer notes and linking them etc.
I don't do any of the unique numbering thing. I label everything in plain english, I don't care. I let the software keep track of the links. I use yaml headers to manage slugs and titles properly.
I am now (for certain subjects I have started) at a point where I can write a fairly long essay or chapter of a book by just opening notes up and reading while writing stuff (almost without thinking) because all the details I've already analyzed are right there.
At one point, I thought the value was going to be to write all these notes, then I can simply stitch them together. SO i was very picky about what i wrote and how they are organized. BUt now I'm not picky about either of those. Because its faster just to rewrite as needed. The benefit is having the key analytical stuff right there, no time wasted re-analyzing or figuring out the flow or logic. THat's where the productivity has come in for me.
SO that's my update!!
