I read this article today about piracy and digital books and agree with the speaker about book piracy.
It seems like the best way to fight piracy is to make it dead simple for people to pay for your content. If it’s good content that people find valuable, they’re totally willing to pay you to produce more of it. And it’s a good thing to let them share it with other people because it gets the word out to more people who may not have seen it otherwise. It expands your readership. Locking your book up with DRM and hunting down people who didn't pay for your book are counterproductive pursuits to the connection you get to make with your readers.
This is one of the reasons the internet has been nice for Radiohead and so rough on Metallica. Radiohead made it easy for people to share their music on the internet and then pay what they felt was fair, while Metallica sent the legal system after their fans who shared the music they loved.
Embrace new directions and take the opportunities that arise to relate and have a dialog (back and forth) with your readers.
