It depends on what sort of collaboration. For things on which I was the sole author, like my dissertation, I leveraged the miracle that is pandoc. Every email my advisor got from me was a perfectly formatted Word doc with a flawless bibliography and he never had to learn what the hell LaTeX is.

But if you have multiple contributors going back and forth, or need to keep long-lived discussions in the track changes panel, you’re better off not trying to teach others a new tool. Unless they have a genuine interest in it, in which case the WYSIWYG editors can be fun.
