I tried Vocal last year. I published 6 stories and earned a whopping 3 cents. Believe it or not that is even worse than Medium. I submitted a seventh story but it was rejected because it "wasn't mainstream enough." I don't like that they have a payment threshold. At the rate of their pay it could be 3 or 4 years before I would ever see any actual money. Also, like Medium, they are not very friendly towards literary fiction. I did a fair amount of reading there but I found very, very little writing of interest or of much quality. I was done with it and decided to stick to writing for pennies on Medium and the reason is because there are so many writers that I like to read here.
