Cory over at Boing Boing links to the FSF’s announcement of their annual campaign to secure funds in support of all the work they do in publishing, maintaining and updating the GPL, the very heart of free software.

If you use any of the GNU library of software tools, and if you use a Linux kernel you almost undoubtedly do, you should consider kicking in whatever you can afford. I’ll be combing through my budget to see what I can spare after my other support commitments (EFF, CC, et. al.)
