This may not be a bug per se:

I posted a link to a ccM upload on my Google Buzz. Someone (colab, actually) read my Buzz and replied out that “re: ccmixter - that’s a bit backwards. They’re sponsored by ArtisTech - but of course fully compliant with Creative Commons.”

Remained clueless for a while until I realised he was referring to the automatic tagline inserted by Google Buzz. Currently says “ccMixter is a community remix site sponsored by Creative Commons”.

Looking into Ivan….thanks for the heads up!
