Miiverse

Miiverse was a social network for Nintendo 3DS and Wii U. It was made by Nintendo and Hatena. It was powered by the Nintendo Network. Miiverse was made for people to talk with handwritten messages. In some communities, they made videos of games. You could use Miiverse with any web browser. There was also an app version. It was planned to be made for tablets and smartphones. All users who got a Nintendo Network ID were given a Miiverse account. They were given their own Mii avatar for that Nintendo Network ID.
