I've been going over some RSS feeds, and I found the following link.

This link is about a technical book from the 80's. I remember something from the 80's regarding books: they where more then just pages, but interactive, and many time more friendly then any good  book or tutorial that we have today.

It makes me wonder, where did we loose the simplicity approach and returend to the more "clean" one, that books must be plain text, not interactive etc…
