In the quest to find out just what creates that horrible large chunk of black space at the bottom of the page when there's only one/a few posts, I found the issue is related to the navigation menu of all places.

Under Content, Game Guides and Release Notes should both have sub-menus, they exist in the page source but are not displayed to users. The Release Notes sub menu is so large that it has a higher height than the content sometimes, and is invisibly making the page have a bigger height than the content.

This is my piece of feedback
