The first thing I tried was hitting the down arrow key to scroll.

The second thing I tried was clicking the blue text, which brought me to Brendan Eich's Twitter page. And then Twitter did what Twitter does, and popped up a sign up/log in dialog in front of the content so I can't actually read any of it.

Pressing the right arrow key was my third guess.

I think normally these are the actual slides that the presenter used. So they were created for easy presentation, not for web browsing.

I have to admit I kind of despise these 'slideshow pages'. They needlessly break the web for a gimmick.

Thanks, I genuinely couldn't figure out how to see more than the title before I read your comment.

I only figured this out because about a year ago I ran into a similar issue and poked around the source for 10 minutes to figure out what was going on. This time only took me 1 minute :) Of course, just like last time, after I realized it was another useless slide deck with no context I left the page.

What if I don't have a right-arrow button? Keyboards are not standard equipment in non-text-entry contexts.

And that it's fucked on mobile.

I clicked around frustratedly for a while before just opening the dev tools and seeing it was a slideshow.

I want to call it a bad user experience, but maybe it's actually a clever way of limiting your audience to web developers.
