Bullshit. Digital can be expensive, and digital projects made without a clue to the reasons you’re making them are almost certainly going to be expensive, because developers have to live too. If you don’t tell someone exactly what you want, or learn to talk to them about what that is, then you’re going to be paying through the nose. Digital isn’t inherently expensive though. Certainly no more expensive than your time is when you’re writing, and definitely cheaper than a billboard on the side of a bus, or in a tube station. Suggesting that the imagined expense of digital is a barrier to even starting is cobblers, and cowardice. A book needs to be in print, be warehoused, shipped and promoted. Even an eBook needs editing, designing and maintenance, and we’re all capable of doing those things.
