An Analysis of Epub3: "Website in a box," and why that's bad

Thought this might interest those of you who, like me, are messing around with ePub files on their readers. The article goes on a few tangents but the core is a good read.

Building a cross-reader ePub today is faintly reminiscent of building a cross-browser website in the early 2000's. Sounds like the complexity added by ePub3 will only make it worse.

Not to mention that when I'm reading a book, I want it to be a book--otherwise I'd go read a website!
