On netzpolitik.org (which covers topics related net politics) is an interview from Markus Beckedahl with Georg. He explains why the GNU project is important, which future challenges he sees, and how FSFE's work looks like. Enjoy the interview (in German).
The author Bob Chassell writes about why he think it is bad to talk about viral if you talk about strong protecting licenses such as GNU GPL. He suggests to call it vaccinates. I am also using this expression when explaining strong protecting licenses, I think it helps people understanding it better (I first heard it in a speech from Georg iin 2004).
