Ever wonder how Nintendo decides what Miiverse comments is displayed in WaraWara Plaze? Well, here is how.

“The most discussed topics in Miiverse – e.g. specific games, applications, boss battles, user accomplishments, etc. – will be displayed on Wii U’s main menu. Before that content is posted to the main menu it will be screened and filtered to ensure that it is appropriate for everyone.” – Nintendo statement
