- Org-mode data format
- Software implementation that understands the data
- Emacs
- ...
The syntax is very well thought out as well. Specification here: (https://orgmode.org/worg/dev/org-syntax.html)Maybe it's a bit late to hope for wide software adoption for the org-syntax. Markdown has in a way taken that space already. But... I'm still hoping! ;)
Org mode has so many fans because of what the implementation (i.e. org-mode in Emacs) can do with those files. It works as an awesome ASCII table editor. It works as a half-decent spreadsheet. It works as a great planner. It works as a better version of Jupyter. And couple other things.
I'm the same with vim (and against I get why people love it).
Most all of my programming is done in an IDE and when I just want an editor (markdown usually) I tend to use vscode (I use it when I have a lot of frontend stuff to do as well, it's TS mode is better than Intellij's).
