I wholly disagree with this after using markdown for everything for a few reasons, but it may work for some people if you really love operating from a basic CLI. Some people also get by with storing everything in plain-text files as well. Why not, plain-text will still be supported as well.

Markdown, especially CommonMark, will likely never provide what you want. Is it convenient when you have hundreds or thousands of files to manually manage? Most likely you'll constantly be searching for ways to make markdown work more like a word processor & CMS, because what you really want is a powerful WYSIWYG content management platform.

I'm not going to judge someone if they are content with basic markdown. It isn't my place to. But to make a statement like, "if it is worth keeping, save it in Markdown" is preaching from a bubble.

I have a tendency to jump between different note-taking services. Markdown seems like it could maybe be a cure for me.. By now i have no idea where I should look for a note I know I’ve taken, is it in notion, onenote, apple notes, and so on..

I migrated from mediawiki to markdown in git 8 years ago and never looked back. The ability to publish to any number of static site hosts, and use any number of editors, some that have preview mode, is rad. Data liberty, data portability, wide support, easy to convert, easy to grep, good enough for 95% of written notes.

My biggest gripe is poor support for tables of data.

That website was the fastest loading website I’ve ever visited.

Handwritten HTML with limited tags works just as well for many purposes (just forbid div, span, and a few others and the complexity you see in most webpages evaporates). The important part is using a text-based format from which information can be extracted even if the fancier display protocols become obsolete.

See, this is why I'm sticking with pen and paper for the really important stuff.

No offence to the apps themselves, I find them especially useful when I need to transfer info from one device to another. But I do not trust anything purely digital for long-term to permanent archiving, especially not Cloud solutions.

Also significantly more reliable in case said info need not see the light of day. Just sayin'.
