I was wondering how the top 10/ 50 were determined? It's weird that pages in the middle of comics, older images, and locked content frequently find their way onto the list. I would expect comic covers and newer images to show up more often! Maybe this is an indicator that users are more apt to browse using the random images than a navigation menu?
The top images are determined by Elo score from which thumbnails get clicked on in the engagement widget (the group of 6 random thumbnails that appear next to/under images). It's not strictly random, it's slightly more likely to show already highly ranked images and new images, although I tweaked it to not show too many locked images recently because I thought the frequent upsell might be annoying.
It's a pretty consistent measure of how appealing an image is. Covers don't show up because they're often not as stimulating as an action scene or as curiosity provoking as a thumbnail with tiny text. There's also the bottom 50 https://satinminions.com/bottom50 which shows a pretty clear bias for old uncolored sketches where not much is happening.
