Like I said yesterday, there is no shortage of markets for short stories. New internet for-the-luv markets open almost daily. Paying markets are hanging in there and reinstating pretty often. I won't lie and say you'll get rich selling short stories. (Though some erotica authors do all right.) Mostly, short stories build your resume and get your name out there. But I'm getting ahead of myself.
Submitting to an online market takes nearly no time at all. There's no lengthy query letter to draft, no sales pitch. It's basically here's my story, "such and such", it weighs in at (rounded to the nearest hundredth) words. Thanks for you time and Bob's yer uncle. List credits if you got 'em, skip that whole bit if you don't. Seriously, editors don't care. Let me repeat that. Short story editors don't care how many credits you have. It's all about the story and no where in our industry is that more true than in the short story markets, especially with us indy types.
So, no pressure on the letter. That one thing makes it super easy to send it right back out there, too.
Most turn-around times on submissions are decent--weeks rather than months, and I'm convinced you'll get a fair read. And there's several places online to find markets. I like Ralans.com.
But really the best thing about submitting to short story markets is that with less time invested in the original product and the marketing of it, rejections don't sting so much. There's also other benefits, like it being more generally likely that you'll get the coveted personal rejection. That's what we'll get into tomorrow. :)
