Guys,
Great idea. I would focus on specialty media. Think things like banking regulations, utility work, law reviews, etc. I think there is pretty strong willingness to pay in those markets and the credibility of the individual authors may carry more weight than magazine brands. Giving those writers a bigger cut might also attract them to the platform. Clearly you need to think about an advertising model here but those are the types of markets I would try to compete in - not serialized fiction.
