I’ve noticed that some CC licenses have deprecated, specially samplin+ and NC samplin+.

There’s a lot of stuff in the site with these licenses. Should it change the status or continue like now?

http://creativecommons.org/...

Mentioned at http://ccmixter.org/thread/... this was coming with launch of freesound.org v2. There will be a blog post about it on the CC site on Monday explaining the many reasons for retirement, some of which may be reasons for ccMixter users to migrate, where possible. Note [nc-]sampling+ will be available forever, they’re just strongly (and now officially) disrecommended.

I notice that ccmixter itself uses BY-NC and only offers two choices for acapella uploads. I agree that some rationalization was neccesary, but I have another foot in the photography and wiki projects where BY-SA is winning. I wonder what are the reasons for the popularity of these two. fascinating to watch this piece of history unfolding.
