I appreciate the attention.

The way I keep notes has changed a lot since I wrote the book, and my experience of notes has changed a lot.

The comments here that are most in line with my deeper experience:

* [sliverstorm:] "If time is precious and every moment is worth preserving, who is going to spend time reading these records?"

This is a very good question, and one that my notebook systems have pivoted around in their evolution.

This is about the purpose of notes, and how that turns into their organization.

I estimate that by my present notekeeping system, 1 in 15 pages of my notes are revisited even after 1-2 years time. I arrive at this figure by opening a notebook from 2 years ago, and asking myself, "How many of these pages do I still regularly revisit?"

I think this is actually an unusually high value -- I'd put most notekeeping systems somewhere in the 1 in 1,000 to 1 in 100,000 range, if they have any pages at all that are regularly revisited after 2 years.

The question is, "What are you keeping notes for?" And this is where the ethic of developing thought comes in.

Which segues straight into these two comments:

* [timtadh:] "Two things fascinated me about the article: 1) the inability of computers to model his thought process and 2) the experience of thinking deeply."
* [kiba:] "I am more interested in how his thought process change and help him solve problem than his notebook system."

I've taught several classes on keeping notes now, and I've found that the main distance between what I'm talking about, and where people are at, is in terms of the ethic of incubating thought.

Our thoughts appear chaotic and unruly, going in all directions at first, but with time, themes and patterns emerge. A programming idea that fascinated you 7 years ago still continues to fascinate you, 3 years later, and then 4 years later again.

Can you develop a thought across time? Everything works by accumulation.

The answer to these questions is to prioritize the development of thought, to make space for additional thought, and to focus on editing and annotation, rather than the focus we see today on the ability to find what has already been written.

That is, today we focus on the question, "Can I find a prior thought?" An important question, but I have solutions to that problem.

The deeper question is, "How do I extend the prior thought?"

And here is where user interface makes or breaks the experience. If you cannot layout the scene, if you cannot apply visual techniques transparently, if you cannot position your thoughts, -- you're dead in the water.

Editing ASCII text files definitely does not function here. There is no annotation capacity. You cannot write "in the margins." You cannot diagram. You cannot vary your font with ease. There are so many ways in which our user interface fails us.

Yes, yes, -- we can make up stopgap "fixes" to these problems, but the problem remains: it's nowhere good as what we have with a pen and paper, even given the capacity to erase, copy, transfer, etc. If a stellar page is revisited only 100 times in its life, (whether computer paper or real paper,) then you really aren't getting much of an advantage from all these sophisticated computer capacities. But the difference in "user interface" is extremely relevant.

I love my computers and my iPhone, but touch, mouse, keyboard, and (today's) pen computer are still no match for a pen and paper.
