Apparently tomorrow, August 28th, is Software Freedom Day.
On August 28, 2004, we will celebrate the first annual Software Freedom Day. On that day, we will make the world aware of the virtues of Free and Open Source Software (FOSS), and encourage its widespread use. We will set up stations in public places to give away informational fliers and CDs with selected FOSS, including TheOpenCD and a Linux Live CD
This is a “a global grassroots marketing campaign” organised by the United Nations, through its International Open Source Network (IOSN) . It sounds like a worthy cause to support, pity I only found out about it on such short notice.
