Explore is a Flickr feature with the intent of showing people "some of the so-called most awesome photos on Flickr." Photos seem to be automatically selected by computer according to a secret algorithm called Interestingness! Explore includes a small sampling of all of the photos on Flickr (currently at 500 per day or about 0.005% of the daily upload volume).
Guess I got lucky! :)
