I've spent some time going through my photos on Flickr, assigning a permissive Creative Commons license to any photo without a familiar face in it, and adding tags to all such photos. In doing so I hope that others will be better able to find and take those photos and use them any way they see fit (so long as they attribute the original photo to me).
Further, it seems prudent to assign a copyright license to my blog posts as well. I haven't yet decided which license, but I'm certain it will be a Creative Commons license - likely the CC By-NC-ND license.
Does anybody have experience with and suggestions for licensing blog entries?
