In my observation, numeric-URI-based systems like Drupal tend to have
minimal Links inside their content pages (i.e. beyond the menu
system), mediawiki-based system tend to have hundreds of links inside
their content. I believe this is so because links inside Drupal pages
usually point to something like http://drupal.org/node/21947/ which
makes it impossible for humans to easily check whether this is an
intentional or erroneous link.
This is off-topic, but for Drupal this is a configuration issue. One of the early lessons in books and tutorial series is how to configure this, and many Drupal sites are configured to use human-readable paths. Drupal.org is not because it has millions of nodes which often change names.
You are correct that most Drupal sites have fewer internal links than wikis, but I think that holds for Drupal sites that are configured to use human-readable paths as well. The cause is more likely in a different interface issue.
I don't mean to spin this out into a tangent about Drupal, just wanted to point out that correlation doesn't imply causation in this case.
