Just in case you weren't aware: You can listen to samples of many of my novels on my YouTube channel. There are presently videos for 12 Hours of Halloween, Blood Flats, Eleven Miles of Night, and many others.
Videos that feature readings of fiction do not comprise a "hot" genre within the YouTube ecosystem. YouTube is more focused on video games, celebrity gossip, profane adolescent humor, partisan political screeds, and similar worthwhile endeavors. A fiction author on YouTube is lucky to get a few hundred views on any given video. I don't think that any of my videos have received more than this.
Nevertheless, the videos are useful for hyperlinking and embedding in other locations (this blog, Twitter, Facebook, etc.) for potential readers who are interested in one of my novels or short story collections.
I completed over 400 story videos during 2016 and 2017. There is already a lot there, and I'm presently focused on writing some new novels and short fiction. So I probably won't be uploading many new YouTube videos between now and the end of the year.
That said, I'm one of those relatively few authors who isn't camera-shy. Video remains a core element of my overall strategy for getting my stories out into the world, and I do plan on jumping back into YouTube in earnest in 2018.
