The Flickr Interestingness algorithm tracks the most interesting photos on Flickr by parameters such as “where the clickthroughs are coming from; who comments on it and when; who marks it as a favorite; its tags and many more things which are constantly changing.” Having a high “interestingness” factor is what gets a photo to the Explore page, which means more views and a higher chance of appearing in external search results.
I would like to look for and visualize the colour trends of these most interesting photos.
