Just part of the transition from big houses to many smaller independent publishers. It will be painful for many, no doubt. I do agree with the article that many "professional" authors may be hurt but I think what we're seeing is a shift in what that term means.
Many more people will be able to break into publishing who could not before. I think what we may see is a growing pie (book sales) divided into many more fragments. As someone who went from 0% to a small slice of that pie, I'm not complaining.
