Speaking as a Workflowy user to your concerns, it's the best of all worlds for me:

- nightly export to dropbox as plaintext and a backup as a type of json format with more metadata. If Workflowy goes away tomorrow, I have everything and can continue in an editor if I like. But until then, I use the pretty web interface.

- multiple device support. I am not going to mess with ssh on my mobile devices. I use Workflowy for everything from extended note-taking and long-form writing to quick pre-set searches on the go for reference; and that's on all my various interfaces (and sometimes other peoples too).

- Workflowy is easy enough for laypersons to view and/or collaborate in seconds. No setup necessary on their end.

I am a happy paying customer of theirs.
