Ink being spilled about Canada requiring companies that host podcasts must be "registered". Assuming even half of it is true (I'm always skeptical), it's fortunately unenforcable. The podcast technology is decentralized; anyone can simply upload an mp3 and RSS file anywhere on the web. Not even the Canadian bureaucracy is prepared to "register" every site on the internet.
Thank you, @adam for making the most censorship-resistant medium since usenet. Your contribution to freedom is appreciated.
