This article is technically on “five reasons for optimism about the future of ebooks” but, really, mostly I’m just sitting over here squeeing about the idea of EPUB3.
Because, seriously. EPUB is basically HTML rendered in a special browser (the so-called e-reader). And yet its feature-set is, like, lagging ten or fifteen years behind easy. EPUB is currently in its awkward Comic Sans and rotating flaming skull GIFs phase. It’ll be very, very interesting to see where it goes over the next few years.
