The discussion has benn possibly excessively abstract, mine included, in that no one has mentioned the actual nature of the links people find helpful to forge. In an ordinary outline, links are parts of hierarchies. In an outline with cloning, they are part of multiple hierarchies. But UR offers still more flexibility than that, and I wonder whether this flexibility is or is not an asset.

UR encourages links not only based on headings that the user creates for some classificatory purposes, but links between bare items. These links can even be circular, so that an item can be both parent and child of the other, in different respects, one should hope.

Is this actually useful, except for a rare situation? When you make all your linkages in UR, are you apt to see any kind of patterns emerge? What have users learned by linking anarchically? Or are the masses of linkages more confusing than the original data?
