DZ Allen last night announced the shuttering of his Muzzle Flash site, where I had published two pieces.
I'm not fond of flash fiction's trademark surprise endings. I'd prefer to write longer shorts or novels, but plans yielding to insight, I've often written stories classified flash by length. I usually don't make money from these stories—probably why many flash fiction markets fold—but once in a while a story presents itself that is best told as flash.
More markets are out there; you just have to look.
