I'd be careful about posting unpublished work on here - Publishers don't like to handle manuscripts that have been out there on social media in whatever shape or form. Use steemit as a forum to test out projects unrelated to your main work. I've serialized chapters of my novel on here (Epiphany , on Amazon Kindle) but I abandoned the project because I had to re-format to suit this site and it just wasn't working for me. It's hard to sustain interest over a long period on here - shorter pieces less than 1000 words do well and you can divide them into parts, but anything of novella or novel length, IMHO, forgeddaboutit LOL!! ( One caveat - I'm just a man, and I reserve the right to be wrong - but wisdom lies in the advice of many counsellors. Solicit others' opinions and take the course that seems best for you) Good Luck!
