A strong Zettelkasten is Line upon Line, one that is built across many years and has many connections. As the zettelkasten grows in size, the number of connections between those atomic interconnected notes increases as well.

It's through the interconnectedness that the power of the Zettelkasten method of note taking begins to manifest itself. The possibility space expands as the graph expands, and allows for "walking" through topics.

Seemingly unconnected concepts can be loosely connected in unexpected ways, making all connections part of the cohesive whole.
