Speaking of podcasts about writing, David Sparks recently guested on Technical Difficulties to discuss how he uses iBooks Author and other such tools to write and publish his Field Guide eBooks. Anyone considering getting into the self-publishing game should give it a listen.
One interesting point that came up in the conversation was the fact that a project created in iBooks Author doesn't necessarily have to be sold on the iBooks Store; it could ostensibly be used as a tool for putting together something special that can be freely shared with friends and family. Or anyone else with an iOS device, for that matter.
