OO.o 3x has over 50 million downloads

As of February 2009, there are more than 50 million downloads of the OpenOffice.org 3.x suite. This number does not include OpenOffice.org that are bundled with Linux distros nor does it include downloads from non-official mirrors.

Truly astonishing stuff. Have a look at http://marketing.openoffice.org/marketing_bouncer.html
