I put CC on virtually all of my Flickr photos. I still get asked permission to reprint them (and once was even paid). It doesn't seem that I get much of an increase in traffic, though....though I've never really tested it by setting the whole collection to non-CC and back. I just don't think Flickr's "interestingness" algorithm would make CC-photos rise higher, as typically the most visually striking photos (also, the photos of models) will not be CC-licensed.
