- the venn diagram of people using emacs and using org-mode seems to largely overlap. That makes it impractical in non emacs heavy environments (aka. the wider industry).
- tooling outside of emacs is mostly not there.
- org mode is a basically similar to other wiki dialects with similar syntax, limitations, tooling, etc. Other than the (emacs) tooling, I don't see a strong reason for preferring it.
The above makes it a non-starter for me personally (not an emacs user) or for teams that have non emacs users (i.e. all teams I've been on, ever). That does not invalidate it as a personal note taking tool of course. But lets indeed not overstate its utility. Some people like post-its, scribbling in a notebook, simply remembering to do stuff, or their super duper emacs setups. Whatever works for you.
