Actually, I've been sort of curious as to how photographers react to Creative Commons ever since I found it ages back.
Apparently the music industry has a love or hate relationship with it, some people love it, some people (namely, industry representatives) seem to be calling shenanigans and warning against it. Personally I love the idea, with images and audio being sent to the other side of the world in a heartbeat, licensing may as well get with the times. Attribution Non-Commercial is my favorite, and the Developing Nations license looks like a good idea.
