In 5 of the site sections, you will see a horizontal tile bar that appears every so often. You can adjust whether this bar appears and how often. There are three main controls:
On/Off: Unchecking the "Show horizontal tile bar" control will simply eliminate it from that section of the site.
General Frequency: The first number is how often the bar appears (e.g. after X number of posts, article tiles, etc.)
Initial Frequency: You may wish to start showing the bar after X number of posts before it goes into its general frequency of every Y number of posts.
