When you save your work in the cloud, with PubWriter, you can share your work you choose with anyone in the world. On your own domain, exactly how you want it to appear.
PubWriter gives you the opportunity to turn your website into an eBook - formatted exactly as you prefer with more functionality that you get with an eBook reader (the options for engaging your readers through javascript are endless).
This is why I'm referring to it as a Cloud Book.
With PubWriter, the browser becomes the eBook reader, or what I refer to as the Cloud Book Reader. This means it can be read on any device anywhere in the world.
Since your own site is sync'd through your own Dropbox, the moment you hit save, the content is published (or updated) for the entire world to see.
It's a different approach to publishing, but one I believe is the future. I go into more details in the PubWriter manifesto.
