I am in the process of launching my maiden book. Yes the website around it would be plone 5. But I want to draw the community attention to something I find interesting. While i did the DTP of the book myself, after I wrote the first draft, I actually created the book on the site. And when I generally reviewed it on my mobile (through the net), it was indeed very good.
I think this area is a low hanging fruit which developers and the Plone team should look at. I am referring to a few features which if added, independent authors could easily use this platform for Ebook.
The additions in my view needs to be towards the commercial aspects of taking a payment or subscription and then of giving access after a payment is done. I have actually not thought through the requirements. Any views on the feasibility and if any work has already happened.
I would be releasing the book on kindle. But it would be a matter of pride for me if it was available though my plone site.
