This is ridiculous... Normal markup and some links for a table of contents should be enough. You can see clearly that Adobe is one of the bigger companies behind epub. It's becoming some sort of ebook version of pdf with way too many features.

I don't want my ereader or book to execute any code. I don't want any Twitter or Facebook stuff in my books. I find it irritating enough that I'm harassed by them as they seem to have become a "feature" of every device I buy. It will be in televisions soon; maybe already is. (edit: I have noticed that the Kindle harasses me EACH AND EVERY TIME to sign into Twitter and Facebook when I put in a rating after finishing a book. I don't even have those accounts, and the harassment cannot be disabled. Therefore I don't put in any ratings anymore.)

Why does everything need to be "socially connected" all the time nowadays, even ereaders (using browsers), and now even books?

Mark my words: these features will have you watching personalized ads in the middle of your books. If this gets out of hand, I'll sell my ereader again, but this time not of lack of content, but because of unwanted content.

I am starting to hate (and fear) Adobe. They hold too many standards. Pdf for documents, epub for ebooks, dng for pictures, postscript for printers, Flash for the Web, and Type1 for fonts. Truetype by Apple has largely been superseded by Opentype, by.... Yes, Adobe. Even many of their programs, Photoshop, Lightroom, Illustrator, Indesign and Premiere are the unquestioned defaults in the media industry nowadays.

Bah. Humbug!
