Compactness

From a reader's point of view, a high compactness indicates that from each node you can easily reach any other node in the hyperdocument, suggesting a large amount of cross-referencing. This might be intended by the author, but it might also indicate a poorly structured hyperdocument that can burden readers and lead to disorientation. In a fully connected graph the user has no clue as to which node should be visited next. It is like reading pages in a book by selecting them from the index.

High compactness poses another problem to the author: since nodes can be read in almost any order it is difficult to make sure that no information in a node depends on nodes that may not have been previously read. A low compactness on the other hand may indicate insufficient links and possibly also that parts of the hyperdocument may be difficult to find or even be disconnected.
