I had to deal with this situation in multiple levels. I manage an anime convention, involving many levels of people -- some wants them on calendar, some wants as a file like PDF, while I also wanted to provide web access to those info, and Org-mode fits nicely with this situation. (and I was a sole user of Emacs/Org-mode.)

As it's just a text data, Git worked great to keep it up to date.

Only thing is that I haven't yet to find the good way to handle automatically managing mutual links (auto generating link from A to B, when I link from B to A -- I'd actually like to know if there's any suggestions.), which would make this process much clean!

You can export org mode files as HTML, PDF, LaTex, even iCalendar. Try C-c C-e to see options.

Ah but I would have to manually copy them between computers, right?

I have two approaches to this: for my own use on different computers, I have scripts that sync the files using git (really I should be using git-annex or dropbox or similar); for sharing to-dos and so on with other people, I use org-trello, and they use trello.

Another useful export format is ODT (and probably ODF).

Org mode files are plain text so your friends will see beautifully organized text files.

Haha, no they won't. They'll see weird stars everywhere and a confusing and weirdly indented chunk of text (they aren't using a monospaced font and their edi^H^H^Hword processor mangled the line wrapping).

At least that's been my entire experience. I wish that weren't true however, and it's not like other text markup formats are any better.

In addition to what LiveTheDream said, you can export to plain text with org-export-as-ascii.

And Pandoc is great (but not perfect) for two way conversions to/from various formats now that it supports org files.

I still keep all my stuff in org files, but it's only fair to warn people that these don't work very well as a format when sharing those files with people of arbitrary technical knowledge.
