I think of poetry as a very inclusive term. Still, it's interesting that people want to make the distinction. I love the magazine Double Room for that reason (contributors have to write about their ideas on the prose poem/flash fiction).
Matthea HarveySome of my favorite poems are "confessional" poems written in the voices of aliens ("Southbound on the Freeway" by May Swenson" and "Report from the Surface" by Anthony McCann), sheep ("Snow Line" by John Berryman) or a yak ("The Only Yak in Batesville, Virginia" by Oni Buchanan).
Matthea HarveyI have poetic failures all the time. Many failed poems. I try not to publish those, though some have slipped into each book, since I can't always tell they're failures until later... or I don't want to admit that they are.
Matthea HarveyWhat I like about prose poems is that they seem to make people uncomfortable - people want to define them, justify them, attack them. Prose poems are natural fence-sitters.
