  My 0.01Euro.

  I have checked one moment ago. From my department, there are 
  2 subscriptions to r-announce and 1 (me) to r-help and r-devel.
  Thinking to the users, my estimate are
  (a) staff and post-graduate students: about 20
  (b) under-graduate students: about 300 (many of these (50 to 100?) 
      can be regarded as 'regular users', e.g., R installed on their
      home computer and used not only for the courses for which
      R is required).

  Looking to the subscriptions from other Stats. department in Italy,
  I suspect that our ratio between subscribers and users is one of
  the highest.
