Miiverse can now be accessed via computer or smartphone. Wii U’s social network has now launched on browsers in its beta phase to see what all your friends are up.
The browser version allows users to view their Activity Feed, friends list, notifications and more but not make new posts and new accounts. To use the Miiverse outside of a Wii U a Nintendo Network ID still needs to be setup on a Wii U. Thanks Joystiq.
There is still no word of when Miiverse will hit 3DS.
