I've revised Rubenerd Show licencing. New episodes will be released under Creative Commons Attribution, and only with Share-Alike if included audio mandates it.
I already eschewed (geshundheit) the No-Derivatives and No-Commercial clauses, because I want people playing my show on theirs, and even if they run ads. Share-Alike imposes similar practical limits, which I don't think are useful for audio. I want people spreading the show!
(It's also in line with my preference for the BSD/MIT licences to the GPL, but that's for another philosophical discussion; along with Vim and FreeBSD being superior to Emacs and [GNU/]Linux).
Attribution is nice and simple. Feel free to take my audio and use as you see fit, provided you reference the show. Done and done :).
