Here's what he had to say:
"I don’t really strategize. Submitting stories for publication is roughly equivalent to buying scratch-off lottery tickets. Most of the time you get nothing. Sometimes you get five bucks. And every now and then you win the big money.
"People say send stories to journals that you like, but I don’t really understand the logic behind this. And by the way wouldn’t you, wouldn’t most writers, like any journal that wants to publish them? I would. I guess they are saying send to journals whose aesthetics hew to yours. That leads to weird ideas about writing though. Like, I write experimental so I’ll submit to Conjunctions. None of this business is really healthy. And my favorite journals -- Tin House, McSweeneys, N+1, Hobart, American Short Fiction, and others -- entertain different aesthetics.
"I’d say send any given story simultaneously to five big places and to five smaller/lesser-known places that seem like journals people actually read, and give it up to whoever gets back to you first. It’s always nice to get picked up by a big journal, but Aimee Bender taught me a long time ago that if you publish good work in small places, it sometimes has a better chance of going far. And most of my stories that have done something, been selected for an annual anthology or an award say, have all come from the smaller journals."
