Some Bugzilla installation stats
If you are curious to know the version running on some well known Bugzilla installations worldwide, I collected this information in a single place: http://lpsolit.wordpress.com/bugzilla-usage-worldwide/. I think this way of doing it is better than writing a new article each summer, as I did for the last three years. This page also lists the approximate number of bugs contained in the DB, to give you an idea how big an installation is.
It’s pretty cool to know that so many large companies and projects use Bugzilla to track their bugs. For instance: kernel.org, RedHat, Novell, Mandriva, Mozilla, WebKit, KDE, GNOME, Logitech, Facebook, GCC, Apache and especially Yahoo! with more than 4 million bugs! I hope even more companies and projects will use Bugzilla in the future. :)
