I too have been angry and frustrated by the shoddy formatting found in many commercial ebooks. I had a frank exchange of views a week or so ago with HarperCollins Australia about 'Flashman' by George MacDonald Fraser. I won't go into the details now, but I told them that I would be ashamed to put out something as poorly produced over my signature, and that I certainly would not have bought the book if I had known how badly produced it was. I did get a response, but only that the book was produced by HarperCollins UK, and they would send the email to them.
I have a suggestion, but it depends on whether commercial publishers read MobileRead Forums, and whether they give a damn anyway.
Suppose each time any of us finds a particularly badly produced book we notify each other through this forum to warn others not to buy that book - something like a 'Hall of Shame' - and copy the details to the publisher, and mention that the comment has been posted here.
We might even need a special subforum for the Hall of Shame. How do people feel about the idea? Would the moderators permit this?
