Vote for your favourite packages automatically

 The popularity-contest package sets up a cron job that will
 periodically anonymously submit to the Ubuntu developers
 statistics about the most used Ubuntu packages on this system.
 .
 This information helps Ubuntu make decisions such as which packages
 should go on the first CD. It also lets Ubuntu improve future versions
 of the distribution so that the most popular packages are the ones which
 are installed automatically for new users.
