Pile of Indexcards

I really appreciate that recently Edward Vielmetti introduced the PoI system on his blog. But I must say one thing to correct and avoid further misunderstanding. Strictly speaking, a chronological order in the PoI system is different from the one of Noguchi filing system (see also introduction by Dave Gray).

I must say that a chronological order in Noguchi filing system is not a simple one. For example, in Noguchi filing system, if one pick up a file from a shelf, it is returned to the one side, right end for example, of the shelf. If you use certain file frequently, it stays at the right end. Same time, a file you don't use will slide to the other side of the shelf. The system is always revised. File you uses frequently only survive in the shelf. A chronological order plus this revision rule is the key point of Noguchi filing system. The chronological order is relatively "loose". It is possible because a number of files in the system may not exceed a thousand ; it is in control even if with such a revision rule.

On the other hand, a chronological order in the PoI system is more "strict" one. For example, when I pick up a certain card from the dock, I must return it where it was originally. You see there is no revision rule in the Indexcardins system. This is why I can't say that this system adopts exactly same chronological order as Noguchi's file system. In fact, it is difficult to change an order of cards in the system because a number of cards easily exceed 1,000 ; a unit of information is smaller than file. If I introduce same revision rule, the system will be totally out of control and easily corrupt. In other words, only the "strict" chronological order can keep a consistency and rigidity of the PoI system.
