Flickr and Creative Commons

I think that Flickr and many other photo sharing sites, have a long ways to come in order to really educate the majority of the public on what the creative commons licenses are and how users should apply them.  I think that the laws and legality of sharing and using photos is still somewhat confusing to the average user. 

I think people like to share their photos, it gives them more exposure as photographers/artists.  I would share some photos, but not all.  I think that some of my photos I want to keep private, however I would not mind other photos being used by others.
