Due to the criteria of frequency and density of links, the pages most
often recognized by the engine [Google] will in turn be more easily
called up by the other users clicking on the links, and we can be sure
(thanks to the principle of lending only to the rich) that the pages
that are already overwhelmingly "selected" will continue to be so.
