Flickr patents "Interestingness".
Media objects, such as images or soundtracks, may be ranked according to a new class of metrics known as "interestingness." These rankings may be based at least in part on the quantity of user-entered metadata concerning the media object, the number of users who have assigned metadata to the media object, access patterns related to the media object, and/or a lapse of time related to the media object.

An awesome bit of code, for sure. A great idea, no doubt. An idea that needs to be "protected" and hoarded and kept from anyone else benefitting from? Hmmmm... hooray for progress!
Peh. Lame, lame, lame.
