I was just thrown off by the asterisks. I still feel unfulfilled by the lack of footnotes I was expecting at the end of the post.
I wouldn't download such an ad supported "enhanced ebook app" thing even if Stephen King had written it. And from me, that's saying a lot. Advertisements that obtrusive would completely wreck my reading experience. Now, a standalone ad before the title page, maybe af ew in between chapters and one in the back - that would be more like those stupid advertisement cards they put in paper books. But NEVER EVER EVER should there be ads on the page with the actual book text! That's just... WRONG!
That's my feedback.
