What we try to do is show some similar apps that are close to the app you already like and enjoy, and show some apps that are a bit different. So, for example, starting from an XKCD comic app you can get to a Cyanide and Happiness or SMBC Comics app -- but you also can in a few clicks navigate to a 9gag or Reddit app. You're navigating along the web in a direction -- you can start looking at photo apps Pic Collage or at games, etc.
