For amateur and self-employed publishers, Apple iBooks may be your digital publishing platform of choice, but publishers producing ebooks at scale seem to be excited about Inkling Habitat, a new cloud-based publishing platform.Inkling Habitat lets users incorporate HD video, interactive features and 3D content through its free program. Users are then required to make the finished product available through the Inkling store (available through an iPad app and through the Inkling website), through which Inkling will take a cut. But users can also sell the finished product through other platforms/sites and Inkling will not take a cut.Given the fact that Inkling CEO called out Apple as a direct competitor, it’ll be interesting to see if Apple still keeps Inkling’s app. The software and user-end licensing agreement makes Inkling Habitat an attractive draw to publishers, but if they lose their iPad app, they’ll also lose users. Then again, they emerge as the “Android” of the digital publishing world.
