Back in 2007, The Onion ran a spoof article about a poet taking an extra five minutes to "vague up" a poem, giving "the piece a level of vagueness more suitable for publication."
It's as true today as it was then. I did exactly that to one of my poems, deciding to feck about with the form a bit, and got it into Riverbabble 28, published by Pandemonium Press.
What was published is on the left; the original version is on the right. I will be applying this technique to all of my poems from now on in order to obscure meaning completely. I call this 'The Muldoon Method'.
