Debian has popcon data, popcon is a default in Ubuntu I think too?

From the man page of popularity-contest:

       The resulting statistic is available from the project home page http://popcon.debian.org/.

       Normally,  popularity-contest  is  run  from  a  cron(8) job, /etc/cron.daily/popularity-contest, which automatically submits the
       results to Debian package maintainers  (only  once  a  week)  according  to  the  settings  in  /etc/popularity-contest.conf  and
       /usr/share/popularity-contest/default.conf.
