A few days ago, someone jokingly asked if Henry Ford had a personal knowledge base in Obsidian... Well, sort of! He had something he called "jot books", where he journaled, kept notes, grocery lists, etc. Not dissimilar to how people use Obsidian. The Henry Ford Museum has fifty of these notebooks: https://www.thehenryford.org/search?Query=%22jot+book%22
How should we quantify the impact of Henry Ford's notebooks? How should we quantify the impact of spreadsheets?
Most people who accomplish anything take notes in some form, because writing is a way of thinking. We love to mythologize the tools and methods of accomplished people because we hope it will let us absorb a bit of their genius. But a good camera doesn't make a good photographer. Taking lots of photos helps.
Should you take notes? Probably. Does it matter what your method is? Probably not. Whatever works for you. Obsidian (or any other form of notetaking) is successful if it disappears and lets you accomplish your work.
That being said, I have never seen such procrastination as with people on the lookout for their ideal productivity systems. People writing lengthy blogposts about the last 0.1% of optimization on their note taking systems as if note-taking was their main job. The thing is: a note taking system doesn't need to be ideal, because as with most tools it matters much more who is using it, how they are using it and for what purpose. A note taking system is like a musical instrument: if you constantly find yourself swapping them because "they don't work" chances are this is a skill-issue, not a problem inherent with the system.
There is immense value in just picking a simple system, sticking to it and only revisiting it if there are real tangible problems. I for example just put a piece of paper on my desk every week and write down the things I need to do that aren't appointments. For more complex things, sketches, etc. that I may need in the next two or three months I use a notebook. For long lived stuff I use whatever. A markdown file in the project folder, a text file on the server, Obsidian. This has served me very well for the past decade.
But my job isn't taking notes, my job is doing the things I need to do, taking notes is just something that helps me doing that.
Let's be fair, this article is about this exactly.
> That is a question that, the more that I look at it, seems completely wrong. (...) How does anyone measure what the contribution of a piece of software is to the world? (...) The tool doesn't make the contribution. The tool enables people to make contributions to the world.
and then tries to challenge quoted articles again to prove/disprove those words.
Yes, but, the _shape_ of something does offer affordances of what it makes easier or harder to do. So "obsidian" vs "saving files on my computer" does seem to be a legitimate question.
I think you have to be somewhat careful with this line of reasoning - the camera put the portrait artist out of business pretty much permanently, and the spreadsheet had similarly cataclysmic effects on the accounting and engineering professions.
Just because these things are tools, doesn't mean they can't distort the world by their very presence. I'd be hard pressed to put my finger on the distortion caused by obsidian et al
But when I relate these activities to learning itself, it becomes difficult to gauge how much of it is necessary. If I don't constantly serialize or test what I'm learning, how do I know I'm learning anything at all? And externalizing so much starts to feel like a burden and gives me less confidence in my own intrinsic ability to just go and do things.
I was going to post an "Ask HN" on this topic to see if other people related to this. If anyone has been in this mindset before and managed to break out of it, I'd be curious to know what helped!
I found reading a textbook, and typing notes into a dumb markdown file with the textbooks name is good enough. Typically: definitions, quotes, and personal thoughts while reading. Did this for stats/comp sci/etc. Obsidian + markdown worked for that, even without plugins. Being able to text search is useful, which is why I don't hand write.
Anything beyond that you have to be cautious about paralyzing yourself from trying XYZ PKM.
Theres a quote from stephen king that goes somewhere along the lines of "during first draft don't try referencing or fixing grammar because it breaks your train of thought". I think similarly, when learning something, choose the thing thats most out of the way (usually the simplest) that is least likely to break your train of thought.
In terms of tracking how much you're learning, I'd be very very slow and incremental in what tooling/methods you pick. For me, I just trust myself after reading/notetaking a textbook. Usually homeworks get very easy which is a good sign. Being able to explain what I learned to someone else is a good sign.
It becomes a problem of organising my thoughts so that I can find them and reconnect them and bundle them together into ideas. Which later might become understanding and wisdom.
Obviously this is not nothing new, Zettelkasten is solving the exact the same problem. And through out history many collections of notes have been found and archived. These systems will benefit much from LLMs, purely for the organizational advantageous.
I have taken another approach inspired by mind maps to create my own visual PKM[1]. It has become a giant scrapbook with notes, videos and imaginary, ideas and half-finished projects, and everything in-between. The advantage is that it's a giant visual program, it's a mind map created using a visual programming environment. I'm constantly extending it with new tooling to help me keep my thoughts in order.
In the end, it's the tweeking at my scrapbook while adding to the scrapbook that then causes more tweeking until something arises that was expected but which is very much welcome.

1. I excelled at my exams without any strange note taking systems;
2. I remember many details down the road, even things I thought I had forgotten. For example, I needed some Linear Algebra, and I was surprised by how much I recalled after 10 years, so much in fact that in 3 days I was on par with when I passed my exam. It would have been worth it to make an Anki flashcard for every theorem?
3. In the exam I used such method I just needed much more time that when I used my minimalist note taking. So much in fact that I question the efficiency of such methods.
Say what you will about Tim Ferris, but maybe he was onto something when he said only learn the bare minimum to get something done and more than that is a waste (4 hour workweek).
That needs to start all conversations in this area. Not everyone had the same goals.
Second, what is your specific problems?
Again not everyone had the same problems. There are common problems with common solutions (often multiple conflicting solutions that work in isolation but perhaps not for your life), learning what works for others can thus be helpful. Beware, not all problems are big enough to be worth addressing for you.
The important part is find what works for you. Sometimes you don't need to measure what you learned - which seems to be your concern- if it is important and you learned it you will remember when needed. Of not you need to look it up again. It can be liberating to realize that you don't need to measure everything. Sometimes that isn't good enough though, so back to the first two questions.
The issue I'm still working on is how do I find such notes when I don't exactly remeber what they were about.
Otherwise you're just gonna be doing busy work to feel like you're doing what you're supposed to.
Do not suppose. Decide what you want to achieve and slice that into things you can do inside of a day.
On the other hand, if you have nothing to achieve, anything goes. Just read, think about it, go for walks.
Just don't get caught in between, busy and going nowhere.
I keep "proofs" of past performance. Like a drawing or a name of netflix series I barely understood or a text I wrote.
Once in months, I check that stuff and see myself understand the series better, see that I do better pictures etc etc.
When I feel anxiety, I check old stuff and compare it to the new stuff. It brings pleasure.
For this reason I deeply hate formal certifications especially in IT. It's too much jumping through stupid hoops as well as the world according to <vendor>. But I'm still known as one of the most knowledgeable people in the company because I'm always building stuff and jumping on new things.
But lately I find IT to be becoming really rigid. We have all this governance and iso bullshit in work now where they want us to be certified before we can even start on something. I've been able to duck out of it most of the time by jumping on side projects but in the end I probably need to move to a smaller company that isn't so much into all the overhead.
Ps I do admire people who can be so structured. I just can't be like that. I have heavy ADHD which is probably the main cause :) But it's interesting to hear.
Broadly, there are two very different kind of notes. First, there are notes whose purpose is to be easy to find when you need to recall some bit of information. Then, there is note taking in service of learning.
These two are very different in goals and thus very different in terms of optimal strategy.
Also, there is note taking in service of creation, where the end goal is neither recall nor learning, but to create notes to share to other people, often for artistic purposes but potentially also for reference or learning. These are also different from note taking for personal reference or learning.
Which is fundamentally a reference sheet, it's not for learning.
That might be why interacting with dedicated PKM-centric communities and content is personally so exhausting.
I would think the latter is the former. Do you mean the idea that hand movements of writing help retention?
Brennan could have gone about a better more interesting route that I would have agreed with more, instead of incorrectly blaming Obsidian and conflating it with a specific PKM framework.
I am an avid obsidian user and have avoided most PKM stuff, and instead just developed a PKM that works for me through slow incremental improvements and changes. The beauty of Obsidian is the plugin eco system, and I even was able to develop my own plugin for what I specifically wanted. I think that's what Brennan basically talks about in his "Question 3" section where he favors just making your own.
I do think that there is "choice paralysis" that people may have when jumping into Obsidian and trying to add plugins too early instead of discovering what works (and what doesn't) for them first.
His final point:
> After researching... well, research, a part of me feels a sense of relief. The fact is that I've been using ad-hoc, improvisational methods for research and knowledge management for my entire life. It's clear I haven't been missing out on deeper, richer understandings by way of more complex knowledge management systems.
I completely agree with this, and Obsidian is one of the best tools to do this! And Brennan corrects this in his update at the end of his article.
I have to admit I'm one of those people that just doesn't "get" Obsidian. Every now and then when I have a specific thing I'm working on, I create a new vault, write one or two notes, and then inevitably never look at it again.
Having experienced all of these methods. I've found myself regularly searching through my vault and referencing older material. While the notes hand-written on a tablet, made it much easier to sift through vast amounts of material I was ingesting at the time. I find myself unable to re-use these notes in any meaningful way. They still exist, I can access them, but I don't find myself going back to them. Old paper notebooks? Most of them are destroyed, lost, forgotten to time.
The knowledge management, with easily indexable and searchable contents, has this invaluable perk of being accessible at a moments notice. Keeping potential of being relevant.
I read a post recently about using a local LLM to OCR handwritten notes that I intend to trial soon:
https://andrewdoering.org/blog/2026/remarkable-local-handwri...
The whole discourse around PKM is a problem of the pluralistic framing in modern society that we hide behind individuality while missing the basic points. "Use whatever works for you" is intellectually lazy, and the opposite isn't an authoritarian ontology that people think they are protecting against.
Instead the basics are this: Whatever system you currently have to store/search/synthesize/and share information CAN and SHOULD be introspected to improve itself. Some functions are matters of time and space cost/benefits, other metric functions are qualitative, but can be experimented against and improved greatly with creativity and testing.
I've been experimenting with this for well before Obsidian existed by using what is probably the best proto-Obsidian -- https://zim-wiki.org
And my gut is, while they can be very useful and it can be rewarding to get a good workflow for yourself, we will not see some sort of revolutionary improvement across humanity strongly attributable to these things, and I think I have a solid why we won't even if it seems like we should.
Roughly, they're attractive looking to our brains because they work just like them, nets and nodes and connections and such -- but ultimately, our brains are actually much better at that exact type of work. These tools can help, but they pale in comparison to human brains.
I found they are too complicated, bloated, not easy to organize notes, not easy to access across devices, not flexible, no manual sorting, etc.
I like simple, concise, flexible and practical note-taking or bookmark management app. So I have created my own note-taking app Metaessen [1] for 2+ years.
Now I am just using my own app and pure text for bookmarks and notes.
Life is short, no necessary to use too complicated softwares.
So it struck me as strange that people devised these extravagant note taking systems because I could easily sense the procrastination rearing its ugly head. The actual work behind the notes is always the difficult part. Not the notes themselves. But it’s good people realize this eventually even if it takes them years to come to their senses.
As for the Moleskine, decades later it sits unused. I went back to cheap spiral bound paper and pens, because my mind does not register any of it as some shrine to my thinking, I’m free to actually focus on what I should be writing about. A few color coded pens just for my own sake is all that’s needed.
The financial investment of that one stupidly overpriced and overrated notebook was enough to paralyze me to the point where I never want to use it.
"German sociologist Niklas Luhmann, as he was famous for his use of the "slip box" or Zettelkasten note-taking method and the achieved output of more than 70 books and nearly 400 scholarly articles. This is the kind of remarkable output that many in the PKM community aspire towards."
I think that is somehwhat misguided. The goal shouldn't be great quantity of output, but great quality.
I think AI has revealed that to us in reccent years. AI can produce endless output. But who needs it, what is it good for? Unless we have a GOOD QUESTION to AI, it's output is not very valuable.
These note-taking apps, you write a lot of notes, but is there an overarching question the notes are meant to answer? Depends on how you use them of course. But I would guess that most of the notes are more "Good to Haves" than "Step towards a definite goal".
Most notes don't probabaly take you closer to the end-goal of your project. You just think they might become useful in the future, so you write them down. Just in case. To feel you are taking good care of your precious ideas. But how much time are you eilling to spend to read them in the future?
Not read it, not highlight it, not copy it out: apply it.
The only way to build personal knowledge, in my experience, is to do things.
And I only want to learn things in the context of doing something.
I read and favourite and bookmark stuff all the time to dig into for inspiration.
But then I choose to build something, and I assemble knowledge on a JIT basis and apply it. LLMs make this easier than ever before.
Everything else is theatre at best, procrastination at worst.
Would love something better than markup but not as CPU intensive as Evernote.
I think people get tied to particular tools and methods and optimizing them just right, rather than adapting things piecemeal in a way that works for them.
Notes can be organized in folders just like in obsidian and Reminders are clean and simple to use. No infinite options to customize, no moving blocks and no infinite properties. Simplicity feels good —- for me —- when it comes to these kind of tools.
These also work great with Codex and Claude Code, and with the hopes of Apple getting their act together with an AI integration, I think it might be the better option to manage one’s writing and tasks.

I see some Apple haters’ cortisol levels rising on this comment. Please, this is not me saying that Apple is better. I’m just saying that it’s a solution I’ve found to work for me, and it may work for others too. Just like your super customized Obsidian vault in your cute Linux machine works for you and others.
- Engage with what you're reading. Ask yourself what the key ideas are, which ideas are new to you, how you would define them, and how they relate to other ideas you already understand.
- Test yourself. Do the excercises at the end of a textbook chapter. Create your own questions and answer them. Quiz yourself at least once a week (on both new and old material). Check your answers and correct yourself (if you were wrong, how, and why?). Use flashcards with a spaced repetition regime (like Anki)
- Focus on your retrieval. Avoid looking things up unless you really have to. Each time you recall something you've learned, you reinforce it.
- Your first encounter with new information may need a small interval of just a few minutes or hours, but you should gradually increase the interval periods between quizzes/flashcards on something. The longer you go between recalling something the more it gets reinforced because you have to work harder for it. Build up gradually.
- Use what you got wrong in quizzes or flashcards to identify what needs work.
- Focus on the material you get wrong, but don't totally neglect things you feel comfortable with.
- Basically, use Anki/spaced repetition.
- Take some time between study sessions and quizzing. (I think of studying like kneading dough, you need to let your brain relax some before you work it some more).
- When studying a subject, interleave different but related topics.
- Topics should be complementary and reinforce one another so that insights from one lead to insights in the other. Examples: calculus and rocketry. Spherical trig and astronomy or celestial navigation. German idealism and eastern philosophy. Etc.
- Once you have a rudimentary grasp of a new type of problem, move onto something new, but make sure to return to this type of problem periodically. (Basically, add this type of problem to your flashcard deck). Don't worry about mastering one type of problem so you can do it your sleep before moving to the next thing.
Some other key things:
- Elaboration: Relate material to what you already know. Explain it in your own words. Visualize it. Imagine it in different contexts (if you're learning calculus, imagine your speed and acceleration while biking in hilly terrain in terms of derivatives, etc).
- Generation: Attempt to answer a problem before you know the solution. This excercises your creativity and gets you looking for similarities to other types of problems you already understand. Before reading new material, make a quick summary of what you expect to learn and how it will relate to your prior knowledge.
- Reflection: take a few minutes to reflect on what you've learned that day. What went well? What could have gone better? What other knowledge or experience does this remind you of? What do you need to work on? Etc.
- Calibration: you need an objective measure of what you do and do not understand. Humans are pretty bad at gauging this for themselves without some sort of external measure. This gets back to flashcards.
- Consider using some mnemonic devices. They can be very effective.
- When reading a textbook, don't bother with crazy highlighter schemes. Research shows it doesn't really help. Neither does reading textbook material more than maybe twice unless you have a particular point you're confused about. What does help is spaced repetition and summarizing the material in your own words.
This all sounds like a lot of effort, but one of the key things to remember is that learning is effort. Struggle is basically necessary for your brain to optimize and form new connections, or even to reinforce old ones, and if you aren't struggling you're probably just doing what your brain is already optimized for, which means you probably aren't learning much.
For text files, I always have one generic TODO.md file that uses the `[ ]` todo and `[X]` done notation, and a couple of more generic text files like "work.md" or "solace.md" for more free form writing. There are also folders and text files for specific topics, like quotes, poems, etc. It's very important to have a scratchpad that you can just open up and start typing without thinking about how to categorize it, because you might lose the precious thread of the thought while debating which category to use, and you can always shelve it later if it's worth keeping. Zero friction to start typing is crucial.
On paper, I use a simple loose leaf and folder system. I used to use bound journals, but since 80% of what I write down is thrown away, loose leaf works better. Have a pile of about 10-20 pages. You fill up a page, and if it's destined for the circular file, dog-ear it; otherwise give it a title and date and move it to the bottom of the pile. When you run out of blank pages, go through and either discard or file each page in an appropriate manila folder. This works better than index cards (which are too small to contain a complete thought) or journals (where it's too hard to discard pages.) Lots of people use ring or disc bound journals for that, but I find that fiddly and not any easier to work with than loose-leaf, probably because I just keep everything at my desk and don't have to carry it around anywhere.
Paper has a massive advantage when it comes to diagrams, design thinking, and mathematical equations. I love LaTeX, and use MathJax on my personal site quite heavily, but its so much slower and less fluent than just writing equations on paper. I've tried tablets, and am really good at using draw.io (now app.diagrams.net) but when you're thinking freeform you want flexibility and fluency above all else and never want to be fighting a UI, which takes you out of the flow state. Ideas are fragile things, especially when newborn; any distraction is an unacceptable risk.
I used to use a custom Tesseract pipeline to OCR the pages I wanted to be searchable, but lately I've just been using ChatGPT, which seems to do just fine with my handwriting. As OCR got better over the years, I actually moved more towards paper, because what's the downside?
So, getting back to the point of the article: PKM tools are stuck in the unenviable position of competing with both paper and ordinary text files, and for me they just don't offer enough advantages.
