@MultoGhost Sorry. Lost track of this. I don't think I agree. The term "creative nonfiction" is, it seems to me, clunky, ridiculously academic, and purposely "big-tenty" (If that makes sense), but in my experience it does mean something specific: nonfiction that uses the techniques of fiction--dialogue, narrative, collage, figurative language, etc--to achieve whatever the writer has set out to achieve.

When it comes to prose poetry, and this is not something I have thought through carefully, I think it has more to do with whether you have a definition of poetry that has a hard line between it and other genres. If someone thinks any arrangement of language can be a poem--which I don't agree with--then, yes, it's "I know it when I see it." But if "poem" is a category with definable boundaries, then prose poetry is the edge case, and people might agree or disagree about a particular work, but they'd be arguing about whether or not it fit the definition, not for their "feeling" that it's poetry or not.

There's a prose piece in my second book that I'd be loathe to call prose poetry, because I don't think repetition and sound patterning structure the experience in the way that they do a poem, but that's about where my opinion ends. There are people who have made a serious study of prose poetry, and I am definitely not one of them.
