We had been using this in earnest at my company since August. It's basically the best tool of its kind—and unlike most other tools of its kind, our copy editors loved it. The thing it was missing was team-editing features. But it had the editing process, which is the one thing keeping people with Word, down.

There are a lot of publishing houses that could use something like this. Editorial workflow is a big weak point as we switch from doing a lot of things in print to doing a lot of things on the Web.
