What does this mean to the average author? As newer Kindles are purchased and gifted this holiday season, and older ones are upgraded, more and more readers may complain that their ebooks "no longer work." Amazon has helpfully provided a "feedback" link to readers to inform them of formatting problems.
Amazon can yank your ebook off sales until you fix these formatting problems. See Article here.
Unfortunately, font issues are not the only reason ebooks can get yanked. Amazon has also started to enforce the lack of Table of Contents and Navigational Points. Here is a Kindleboards Thread. This is unfortunate, since Amazon allows authors to upload Microsoft Word documents directly. But the .mobi file that results from it does not have a TOC entry or NCX Navpoints. [See article I wrote about NCX Navpoints and why they are important.]
Amazon can and will continue to change their software with no guarantee that previously generated ebooks will be compatible with the new versions. While it would be nice if Amazon provided a conversion program from old Kindle version to new, in the meantime, authors should contact their ebook formatters and make sure their .mobi files are compatible with the new standards.
If you have this issue, don't feel bad. Even J.K. Rowling's latest book had the font size problem. See Article.
