Nothing ages as well as plain text; it has been the same since, well, files were invented. Markdown is just a very thin layer that gives the plain text some structure, and allows it to be rendered and displayed in an aesthetically pleasing way.

I have always taken notes. At first on paper - there are still many handwritten notebooks somewhere in the archives - but for the last thirty years or so most of them, if not all, have been digital. And digital always means an application and a format. I have tried a lot of them.

While doing so I made pretty much every mistake one can make when it comes to choosing an application and settling on a workflow. What follows is a tour of the graveyard: a long line of tools, most of them now dead, and the lesson each one charged me on the way out.
