"Miiverse is a service accessible via Nintendo's Wii U game console that lets you communicate with other players from around the world."

Miiverse is the Wii U community for sharing content. Its interesting because it recently became available from any-ol browser. Its really cool to look through the content people have posted and so far seems to be user created fan art.

A few cool communities I have enjoyed:

Super Mario World: https://miiverse.nintendo.net/warawara/14866558073024996828

The Legend of Zelda Series: https://miiverse.nintendo.net/warawara/14866558073007174237

Its awesome to see Nintendo opening up its systems to a broader web.
