Flickr recently added a new way to plow thorough the millions of photos on their site. It’s called Flickr Explore, and it’s kind of a dynamic rating system for cool photos that is based on several variables (which they call “interestingness”).
There are lots of things that make a photo ‘interesting’ (or not) in the Flickr. 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. Interestingness changes over time, as more and more fantastic photos and stories are added to Flickr.
The interesting photos are broken down by month and day, so you can take a look at the coolest photos for the day or month of your choice. There are some really neat images up there!
