1) Nobody reads Kindle Singles. You'll notice there's no metrics anywhere on anything listed.

2) Nobody reads short fiction. None of the short fiction sites where actual fiction is traded and sold are even mentioned. /r/nosleep? Gimme a fuckin' break.

I actually discussed short fiction with my agent yesterday. I'd mentioned that I had a bunch of screenplays doing nothing, but that I could probably turn 'em into novellas or short stories or whatever, as well as a lot of the ideas I've been developing with a few different producer buddies. I asked her if I should spend the time.

Kindle Singles never even came up. She said that it certainly couldn't hurt, so long as I didn't lose my focus on what mattered (novels). Know what my mentor said when I talked to him about self-publishing?

Amazon is uploading something like 250,000 self pubbed ebooks a month, and for every Hugh Howey there are a million ebooks that sell fifty copies and all to people with your same last name.

Tor has some short fiction for free but that's mostly to build brand and give authors a proving ground.

Sea change? Hardly. This article quotes that tedious fucking Future of the Internet survey whereby Pew cherry-picked a bunch of "experts" and asked them leading questions. It's about as scientific as asking Jim Kramer what stocks he likes 8 years from now.
