That's true, but they also are very selective and pay very little of the actual profits to the author. My project will help any author, even those with the standard publisher, but it's really aimed at finding the good writers from the flood of newly "published" authors on Amazon. There's so much noise due to the sheer number of self published authors it's really hard to find anything. It's like the Netflix problem, you spend all your spare time going through looking for something by the time you find it, you don't have free time anymore.
I would love to know more if you are planning to do something similar for mobile games. As a mobile games developer I know that something like this will resonate with a lot of mobile game developers
I hadn't really considered games (or even games and apps), but now that you bring it up, it seems like the perfect fit. I think it's certainly feasible to merge the two ideas into the same solution.
