"
Among the categories not actively tracked at this time are: perennial sellers, required classroom reading, textbooks, reference and test preparation guides, journals, workbooks, calorie counters, shopping guides, comics, crossword puzzles and
self-published books."
There goes the chance for accurate popularity rankings of ebook sales. It doesn't matter if Amanda Hocking sells 15,000 ebooks in a week; they won't be showing up here.
I wonder how big a publisher has to be to qualify?
