what is the Miiverse?
It was a sort of social space Nintendo ran on the 3DS and Wii U. Kind of combination chat room and message board with a space where Miis (Nintendo avatars) could “hang out”. It could also be used to send messages though games, like you could leave a message as a sort of note in Mario Maker or Splatoon. I thought it was kind of cool, tbh.
not sure if I’m too old, too young or too poor
It was shut down in…no. 2017 was not 7 years ago. No.
Specifically the issue is that two letter TLDs are reserved exclusively for countries/governments. So far only one exception has been made to this rule, .su for the Soviet Union. So another exemption is certainly possible.
