This is a cool idea and is fun to explore. It would be cool to be able to revisit a page/topic via the journey view. (Perhaps you can, but I'm unable to on Firefox iOS). I think it's interesting that each time I revisit a topic, I might be given a different set of choices; leading me down a different branch. Thanks for sharing!
I opened this on a mobile device, and it only shows the top and bottom topic buttons. I was pretty confused until I tried turning on "desktop site" in Chrome and saw the left/right buttons.
Having only a linear track of topics kind of undermines the overall idea!
So is down "deeper" into the rabbit hole? Or is down more specific and up is more general? Or is it just a related topic (meaning up and down aren't different in any way)?
Cool idea. I’d suggest a few tweaks to improve text formatting. Justified text generally doesn’t read well on a device. Better to justify left. And paragraph breaks seem to be lost, which makes it harder to read and scan.
Great idea. Your site may have been hugged to death, but if it's supposed to be working now, please check on Safari: viewing a topic shows a blank scrollable rectangle where there should be article text, and not much else.
I second another commenter's idea of a minimap: let's visually build the rabbit warren! Just like this:
