Anyone any idea how this works, what algorithm they use?
I look at it every day and have noticed recently that, especially near the bottom of the page, there are multiple images from the same poster(s).
I've had a few images of mine "Explored" but absolutely no logic to when/how they have been selected.
Selection certainly doesn't seem to be on image quality as there is a mix of stunning images, and some poor ones IMHO.
