Not unless you work alone. When you work with other people, it's important to use a common format for the benefit of the group. Trying to force other people to use emacs won't win you any friends.
Org exports to anything including utf8 plain text with a nice style reminiscent of IEEE RFCs.
Without using Emacs Org-mode however, you're stuck with something that only you can properly enjoy and edit, so everyone who doesn't like Emacs is SOL.

If you are more of a vim person and don't like emacs modifier keys, I suggest checking out spacemacs.
Oh no, I'd rather use a modern editor. Both are cults that need to die.
