How well does it do with anything that's not just a pastiche? It's easy to throw in the tics of somebody famous, but can it actually do what a real writer does: focus on what's interesting, build a flowing narrative, target the material to the audience?

Exaggerated voices might give you variety, but I don't actually want to read a piece on the style of any of those voices. I would, however, be intrigued if it could write like me, or like any of the famous nonfiction writers who I've consciously patterned my style after (Isaac Asimov, Mary Roach, Cecil Adams, Michael Pollan)?
