First of all, thank you for the list. It’s useful. I do wish Medium had a bigger focus on fiction and not mainly startup tech and motivational stories.
As my part, I have just created a new publication: https://medium.com/dangerous-stories
It has a whopping 0 subscribers at the moment, but I am hoping to change that fast.
Not sure whether you want to add it to the list or not, considering how fresh it still is; up to you.
