ref. : Comment from Rick
As Rick mentions in the reference
above, writing manual of the "PoI system" is an example of the PoI
system itself.
Each article corresponds to a single indexcard. Same as analog
system, I use title, small number of tags (3 = Record, Discovery,
Reference - GTD), timestamp, link, and piece by piece contents.
They are random in contents, but keep in chronological order in the
"Blog" page. Writing article
in the Blog page is kind of stress-free because I don't need worry
about the order. It is nothing but the indexcards in the Dock in
analog system. Thanks to the HTML and blog, the idea of analog
system is easily connected to the digital system.
For tracking newer contents, the "Blog" is o.k. For sharing with
people, however, it is more convenient if the articles are
reorganized and classified, as we see in a usual books. This is a
purpose of the "Selection" page. The articles are reorganized to
construct a manual of the "PoI System". Even after such
classification, it is easier to insert new article/chapter since
the articles are piece by piece like LEGO. This
manual is growing.
Perhaps we can write a book from indexcard in this way
