The main problem with formatting through Createspace is that they aren't working with your cover designer; if left unguided, they will just choose random fonts that probably don't look too bad, but also don't match your cover design, leading to a very rough and
fragmented reader experience.
Through digital storytelling, you can invite
readers to interact and experiment with your stories, rearrange or find your own path through the
fragments of an essay, even «play» your first - person
experiences.
