Flickr has just released some new features organized around their the nature/relationships implied by user activity around the images on their site, an interesting expansion/improvement on their tagging structure.

Interestingness creates a daily page with the most ‘Interesting’ pics uploaded as defined by how favored the image is, how many comments exist for it, and how widely distributed the user interest happens to be. Very slick. The other new feature, Clustering, groups tags by concept. So the “cute cluster” gets broken in to “cute kittens,” “cute puppies,” “cute babies” and “cute smiles.” Bush gets broken into ‘protest president politics’, ‘green-flower-nature’, ‘grafitti-sticker-stencil’, etc. The flickr blog discusses the new features. Very slick stuff.
