I'm on Vocal. I was a Vocal + member for a while and entered several contests. The problem I have with it though is that it feels a lot like Wattpad. In that, to get anywhere you have to promote yourself. It kind of feels more like a popularity contest rather than one based on the authors with the best writiing winning the contests. I don't like that about Vocal at all. I eventually just earned all the bonus cash and then canceled my Vocal + membership. I'm too much of an introvert to do the socializing/networking needed to do well there.
