Flickr adds features
I'm intrigued by the idea of clustering - associated tags for groups of like images, such as the Michigan Clusters here. It made me realize I need to pay attention to my tagging. If I want labrador retrievers and get to this page, I get to see all the variances in tags for those sweet yellow, black and chocolate hounds!
One of the benefits of pointing folks to clusters of images is that they will find more images that might not have appeared with just one tage. Ponder then, how we might set up our catalogs with this method. Here's the history cluster page... food for thought yes?
