Flash Essays?

Martha Nichols takes a stab at defining an emerging genre:

I love essays for many reasons, not the least of which is their rambling quality. But now, I also find myself drawn to flash essays. At a thousand words (give or take a hundred), flash essays are very short compared with the classics. By “flash essay,” however, I still mean an essay—prose that’s driven by ideas rather than the narrative techniques of creative nonfiction. Flash essays may include an anecdote or two, but they’re not memoir. They’re not “lyrical.” They don’t narrate a personal story in the second-person (you went into 7-11, wondering if the blood running down your legs would pool around your socks) or third-person voice. Flash essays resemble a first-person opinion piece rather than a fictional short story.
