Always worthwhile perusing The Passive Voice, but I’d particularly like to direct your attention to this posting. Do click on the button to read the comments, as there’s an interesting discussion going on about the issues raised.
My two cents? John Dvorak is absolutely correct about the Kindle and other e-reader devices being essentially a new medium, and not just the old print medium ported over to an electronic device. The differences are so significant that it’s going to change things for both readers and writers, in ways that we are just beginning to perceive. And as I maintain in one of my comments in the Passive Voice discussion, a new “rock ‘n’ roll” environment is being created, in which some writers are going to flourish and which other writers will not be able to handle.
