Apparently the note-keeping system is a work in progress:
> PS: Many people ask, so I’ll just note here: no, I haven’t made this system available for others to use. It’s still an early research environment, and Premature scaling can stunt system iteration.
For example, if TV Tropes switched to an interface like this, I bet way more people would get lost down rabbit holes, and they'd go deeper and last longer.
Admittedly, I'm not much of a note-taker, let alone an Evergreen note-taker, and so far I haven't been sold on the idea. Essentially, I'm just too lazy. (I've found a lot of other very insightful information in this quasi-blog, though.)
I'm more hoping for a good neural interface to come out within the next five or so decades, so that this whole process can happen with very little effort and work almost automatically. Potentially insight-generating prior thoughts are pretty lossy when they're just in your head, as you describe it, but a neural interface and associated organization system could possibly eliminate this lossiness problem. I acknowledge it may take a lot longer than five decades before such a thing is practical and seamless, but it's just a hope.
At the end of the day, what I think I personally want right now is a hybrid note-taking, list-making, bookmark/document-organizing, mindmapping, knowledge base/wiki, table/chart-making, scheduling, planning app with an interface similar to this one, where it's easy and fast to follow different nodes, see how they relate, and unwind the stack at any point. I understand such a project is probably way beyond the scope of anything you're trying to do, let alone something you want to build a whole business around.
For reference, a lot of what I do is investigative and research work (generally centered around network security). This rarely involves long-form prose, and is more like trying to map and discover connections between lots of different kinds of small entities and findings. But I'd also find this valuable for more typical business use cases, like what Notion is generally used for.
Basically, I just wish apps like Notion, Coda, and Nuclino would implement an interface that's as smooth and useful as this one. These apps are all basically just trying to clone each other and are using interfaces that could've been designed in the 90s, rather than trying to fundamentally alter the experience.
I discovered Roam https://www.roamresearch.com/ and then org-roam https://github.com/jethrokuan/org-roam .
Roam looks closer to what's on the website, but org-roam would probably fit better into my existing note taking workflow.
