post: Requiem for a Fractal Forest

I've been thinking a lot about the treehouse and I feel like it's time to say goodbye to the tree format.

+title = "Requiem for a Fractal Forest"
+
++++
+
+
+It's been almost 2 years since the treehouse's inception, and there've been a lot of changes in the project throughout.
+It all started on my holiday in August 2023, when I was bored without a computer.
+Reading [Lobsters](https://lobste.rs), I stumbled upon someone's website, and it made me think a lot about how I could make a website I would love as an outlet for writing.
+A website that would truly be a reflection of myself, my own values, and my own quirkiness.
+
+I opened the A5 notepad I had on me during that trip, and started sketching.
+
+A website made out of bullet points.
+A tree of paragraphs, nesting forever and ever, where in every collapsed branch you could find something more.
+And it would grow into an ever-more-deeply-nesting fractal forest, a rabbit hole to suck you in for hours.
+Imagine [Vsauce](https://www.youtube.com/@Vsauce), but on a blog, and if all the tangents were optional.
+
+I was really enjoying [Logseq](https://logseq.com/) at the time, and it was my primary source of inspiration for the treehouse.
+It just felt like a natural way to organise thoughts, so I wanted to create something like it, but without the lagginess and chugginess coming with a bloated frontend app written in Clojure.
+
+And that, my friends, is how the treehouse was born.
+
+
+## The implementation
+
+When I came back home, I jumped straight to my code editor.
+First a data format. Then an HTML generator. And then some CSS to style it.
+
+The first version of the treehouse was up and running.
+
+It wasn't much, but it worked.
+It proved the concept, so I started fleshing it out.
+
+- I added some JavaScript to make the navigation more friendly.
+- Fixed some UX details of the `<details>` element that bugged me.
+- I made it so that branches could expand into lazily-loaded trees, so that you wouldn't have to navigate away from the main page.
+- I made it possible to permalink to branches of the tree, so that you could link parts of it to your friends.
+- I wrote a script that would generate unique IDs for branches for me automatically, so that I could just run `treehouse fix` before a commit, and everything would be linkable.
+- I added dates, so that you could keep track of when something was updated.
+- [And so many more things.][page:treehouse/changelog]
+
+And of course, alongside all those technicalities, I was writing.
+
+The treehouse is single-handedly what taught me to write regularly about my thoughts, observations, insights, and pet peeves.
+And through that, I taught myself to _Write_. \
+Text. Essays. Prose.
+
+The treehouse has been on my mind as my main project ever since I started it.
+
+It just resonated with me so strongly.\
+I cherished it like a beloved friend.
+
+Everything I did revolved around the treehouse.
+
+Most side projects I did were features, improvements, and weird experiments.
+Like that one time I wanted to add a sort-of-visual-novel-type-of-thing to the website, so I started banging out a whole [Twine](https://twinery.org/)-like story graph editor.
+
+It was all incredibly fun.
+
+
+## The limits
+
+But throughout this whole process, I was constantly running into problems with the tree format.
+You see, the UX just plain _sucked_.
+
+By that I mean, the basic UX of reading pages was pretty bad.
+It felt more like reading a braindump than a polished post, even when I spent hours on structuring, proofreading, and everything.
+
+The nesting was distracting.
+The more of it was there, the worse it would get.
+I pretty soon learned you gotta dial it back down to the absolute minimum. 1--3 levels is enough.
+Root for introduction and headings, 2 for heading content, and 3 for tangents.
+
+But it never felt _right_.
+As you expanded branches on the main page, they would drift rightwards.
+The indentation would quickly get out of hand, eating away all your precious screen space.
+I added indent guides to help combat it, but they didn't help.
+It was like browsing an overly nested folder.
+Probably because it was _precisely that_.
+
+The UI around it just felt like a huge distraction.
+Hovering over a branch always caused something to fade into your view to signal it could be interacted with, and I feel like it resulted in a lack of sense of stability to the pages.
+It was detracting you from the actual content of the website.
+
+It was a fun quirk, but not much more than that.
+
+I was also reaching the limits of the structure.
+A tree can only have one parent, but what if a post fits more than one category?
+Where do I put it then?
+
+And what if I wanna edit posts on the web, or add a section for short tweet-like braindumps, or something?
+
+It was all incredibly limiting.
+
+
+## The breakpoint
+
+The moment I decided it was time to let go, was the moment I needed to do a layout change that'd be impossible with a tree.
+
+I wanted to add my fursona to the right side of the screen.
+
+Whatever I did, it would eat away too much space, and result in a feeling of imbalance.
+I had to eat away all the padding from the left side, but then the text felt too cramped.
+It was much too close to the edge of the screen.
+
+The only real solution I could see was to limit the page to a smaller width, but that didn't work with the amount of UI elements tree branches had.
+
+So I abandoned them!
+
+Welcome to the new treehouse.
+Or, rather, just house, because there's no longer a tree.
+You can call it a _meoooow~_house if you insist. :ahyes:
+
+---
+
+But!
+
+Even if it's not a tree in structure, it still has to support the tree format for backwards compatibility.
+I wouldn't wanna have to rewrite all those pages I've accumulated throughout the past two years.
+
+But it's the end of an era.
+I'll slowly be rewriting _some parts_ of the site to this document-oriented format, just like this page.
+But maybe that isn't such a bad thing?
+
+There are lots of ways you can make a really fun blog post.
+[This one comes to mind immediately](https://modem.io/blog/blog-monetization/), and honestly---would you be able to make something that amazing with a tree structure?
+
+Because I wouldn't.
+
+So... welcome to the new treehouse :3
