I wish I could just figure out what content is actually on this thing and skip to the parts that are interesting. Just because people can reveal.js doesn't mean they should. ugh

It's reveal.js and yes, confusing.

Don't think too much, just hit 'Space' and it will guide you correctly through the slides.

Altough even the guided tour feels spatially incorrect...

I was very interested to see a presentation about D3.js, I struggled to wrap my head around it a few days ago and left for simplier libraries. I opened this presentation and I can't figure out in which order should I visit these pages. I closed it in anger.

Good intentions, awful execution.

check out http://www.dashingd3js.com - I wrote it and it starts at the basics and goes from there...

Go right till you see a down arrow, go down until you can't go down further, then go right, and repeat. It's silly and unnecessary, yes, but not that hard.

Just use the space bar.

On iOS?

You can press <ESC> to see an overview of the whole presentation - which is interactive.

Agreed. They look cool, but they are usability disaster.

It really depends on who your intended user is. If the slides are intended to form a presentation (quite likely), then the user is often the person making the slides in the first place. In such cases they're not a usability disaster at all. Rather, they're really helpful (being able to switch between different sections, or miss sections that your audience already knows about easily is really useful).

On the other hand, if the slides are intended for reading, then yes, they may be a usability disaster. But then, slides aren't going to be the best format for reading anyway.

Exactly. Thanks bro.
