I just wrote a short entry what I did for Ogg vorbis this month. http://blogs.fsfe.org/mk/?p=538. There I also give some examples what you could do to help Free Software, Open Standards, and Ogg vorbis without too much afford.
As already announced there, I already asked on http://www.dradio.de/service/kritik/ if Dradio can provide their podcasts in Ogg vorbis, too. During the DFD award Dr. Günter Müchler (program director Deutschlandfunk and Deutschlandradio Kultur) asked us to always send them ideas and criticism. So do that for Dradio and also do it for other websites who only provide mp3 or other non-free formats at the moment. There are two days left to rOGG on in April!
Best wishes, Matthias
