Kind of. But short fiction isn't "rising" by any metric you can come up with. There isn't more of it, what's available isn't better, and authors aren't making more money for it. I say this as someone who writes short fiction, reads short fiction, and has attempted to earn money with short fiction. The market is smaller than it was, the audience less dedicated and the sources for remuneration ever scarcer. Yeah, there's a million people on /r/nosleep but apparently this chowderhead didn't know that nosleep was an offshoot from 4chan was an offshoot from newsgroups was an offshoot from the pulp traders of old.
I'll take a 'zine over markup any day, but I can't anymore.
