To my great joy, today I discovered that two of my favourite radio stations - Deutschlandradio Kultur, and Deutschlandfunk - have recently started streaming their broadcasts in the truly free Ogg Vorbis format. (Better quality, too :-)
Since these are public radio stations, they're not just doing their listeners a favour. They are in fact fulfilling their obligation to make their broadcasts available to the public, as in "really everyone". I hope other radio and TV stations will follow them soon.
I'm glad that I can finally get this dish of my internet radio diet without suffering the sour taste of patent-encumbered mp3. How about writing them a nice email about it? It's good to be able, for once, to commend instead of criticise.
