Creative Commons licensing and Flickr

I don't think Flickr does enough to promote the use of Creative Commons licensing. If someone is not familiar with Creative Commons licensing, it is a way for photographers to indicate under what conditions they would allow reuse of their work. Some of the options are Attribution meaning that others need to give you credit for originating the work, Noncommercial means others can use your work for noncommercial purposes but not to make money, No Derivative Works means that others can use it but only as is, and Share Alike means that if derivative works are created they must have the same licenses that you assigned to your original work.
The reason I don't think Flickr does enough to promote this is because nothing appears about Creative Commons licensing on the individual's home page to let anyone know that this even exists. They do mention that you can let just your family and friends see your photos or can make them public. I had to search the menus across the top of the page and find Creative Commons under explore, so I feel that unless someone is specifically looking for it or just exploring everything, they might not find it.
I think some people allow their photos to be shared because they would like others to see what they created. I think I would allow it to be shared as long as I knew how it is to be used and depending on the subject of the photo.
