If a writer lets software dictate his style, then he's hopeless. But I think this can be a good tool for helping you introduce more variety to your writing.

It can help open up stylistic choices as opposed to auto-pilot writing. We've all written something with nary a thought, and usually it stinks. You don't have to follow its recommendations, but it can make you stop and re-evaluate what you've written, and that makes it more useful than one might imagine.

As a first-line editing tool, I think it's clever, don't you?
