Index cards for commonplacing?

I know that Robert Greene and Ryan Holiday have talked about their commonplace methods using index cards before, and Mortimer J. Adler et al. used index cards with commonplacing methods in their Great Books/Syntopicon project, but is anyone else using this method? Where or from whom did you learn/hear about using index cards? What benefits do you feel you're getting over a journal or notebook-based method? Mortimer J. Adler smoking a pipe amidst a sea of index cards in boxes with 102 topic labels (examples: Law, World, Love, Life, Being, Sin, Art, Citizen, Change, etc.)

How does this happen?

Is it the idea of "personal responsibility" and "pull yourself up by the bootstraps" philosophy combined with lack of any actual support and/or education?

There has to be a better phrase or word to define the perverse sort of philosophy espoused by many in the Republican party about this sort of "personal responsibility".

It feels somewhat akin to the idea of privatize profits and socialize the losses. The social loss is definitely one that is pushed off onto the individual, but who's profiting? Is it really so expensive to fix this problem? Isn't the loss to society and public health akin to the Million Dollar Murray problem?

Wouldn't each individual's responsibility be better tied to the collective good as well as their own outcomes? How can the two be bound together to improve outcomes for everyone all around?

This sounds great, but what are the "costs" on the other side? How does one balance out the economics of this sort of housing situation versus amenities supplied by a community in terms of culture, health, health care, interaction, etc.? Is there a maximum on a curve to be found here? Certainly in some places one is going to overpay for this basket of goods (perhaps San Francisco?) where in others one may underpay. Does it have anything to do with the lifecycle of cities and their governments? If so, how much?

As Lynne Kelly indicates, knowledge is a broad public good, so it is kept by higher priests and only transferred in private ceremonies to the initiated in indigenous cultures. In many senses, we've brought the value of specific information down dramatically, but there's also so much of it now, even with writing and better dissemination, it's become more valuable again.

I should revisit the economics of these ideas and create a model/graph of this idea over history with knowledge, value, and time on various axes.
