The commenting and forums function of Tapastic has almost nothing to do w/ the Books section of the app, haha. We actually use a service called Discourse for our forums (and FUN FACT: we useddd to use a service called Disqus for our commenting system during the early days of Tapastic).
The Books section would need a lot of features to be built out in order for us to be confident enough to have it operate as an open platform, similar to Tapastic.
It's not really a matter of whether we want to do it or not - we do want to do it.
I'm a firm believer in the democratization of storytelling, it's the entire ethos of Tapastic/Tapas. I want everyone to have a chance to tell their story, and we want to build the best possible tools to help those creators succeed.
Yup! We actually work directly with all of the creators on the Book's section to upload and build their series, so in terms of scale, we wouldn't be able to handle having it an open platform right now.
Hm, currently all of the Books have the new business model applied to them - I'm not sure if we'd be able to accommodate that. However, there are plenty of other really great services for that.
