Confusion and Complexity: High time to prune the Creative Commons licenses?

Confusion and Complexity: High time to prune the Creative Commons licenses?: "In a recent blog, Nina Paley, the animator behind the free-licensed animated film, “Sita Sings the Blues”, complained of the enormous confusion caused by poor differentiation of the Creative Commons licenses. In particular, there’s a great deal of confusion over the difference between “NonCommercial” and “ShareAlike” licenses. Maybe the Creative Commons licensing system is still too complex? I’d suggest that only three licenses are really needed: “Attribution” (CC By), “ShareAlike” (CC By-SA), and “NonCommercial” (CC By-NC), and that the others are essentially deadweight that’s holding the movement back."
