I figured out you could use the space bar to advance through the "slides", which made the presentation just about usable. I then instinctively - and possibly stupidly - tried to use backspace to go back a slide. Obviously, I arrived back at HN. I didn't go back to finish reading.

Interesting subject matter, poor presentation.

just use the arrow keys to navigate back and forth trough the slides

Ah. Much better.

I had the same problem as other posters--this presentation more or less breaks scrolling (it still works, but is very awkward).

Using the left/right arrow keys to navigate the presentation works quite well. To bad that navigation tip isn't included on the first slide or on that persistent gray bar or something. It makes a huge difference.

Fix your web browser settings so backspace is pageUp.

Wow, tough crowd.
