A lot of responses here are very typical of the greater problem. The "I support going green as long as it doesn't affect me too much" school of thought.
I think this is a great idea and will support it wholeheartedly. I think the very small population that feel the need to keep their collection "protected" and essentially looking uniform on the shelves by buying regular Blu cases, will not have an impact on the good that this initiative is doing.

This post isn't meant to start any type of flame war and if the Mods feel that it is, I have no issues with it being deleted.
