This page displays exactly nothing with JavaScript disabled. I realize that no js makes me something of a Luddite, but there are solid reasons for turning it off, particularly on mobile. Is it really too much to ask of google that the text of a presentation in some way live inside HTML? Novel concept, I know.
Javascript is like Flash, it's great for the author of a page to show off, or force an ad on you, but how does it actually benefit the end user? Not at all, never has.
