Yeah...it's happening. And the lack of people currently discussing it here on Nintenpedia may explain why.
Here's the full explanation by Nintendo themselves:
"End of Miiverse Service Announcement
Hi everyone, it’s Tom at Nintendo. I have an important announcement:
On November 7th, 10:00 pm Pacific Time, we will permanently close the Miiverse service.
We thank you very much for your amazing support. It has been a great privilege for me to serve as your Miiverse guide, and to see people who enjoy similar gaming experiences connect with empathy.
After the service ends:
• You will no longer be able to access Miiverse from the Wii U console, Nintendo 3DS family of systems or from an internet browser on PCs or smart devices. All Miiverse services will become unavailable, such as viewing or making posts, and messaging with friends. However, for a limited time, you will be able to make a request to download all the posts you’ve made up to the day of the closure.
• For Wii U and Nintendo 3DS games that support in-game Miiverse functionality, these features and services will no longer be available.
• Miiverse posts will no longer appear in the Wara Wara Plaza on Wii U.
Information on downloading your post history:
By making this request, you will be able to download your posts – plus any screenshots saved to your album – to your PC after the Miiverse service has ended. To use this download service, you will need to have a Nintendo Account linked with your Nintendo Network ID, and must make the download request before the Miiverse service ends. To find out more about this service or to make the download request, click on the “Information on Downloading your Post History” button at the top of the Miiverse website. For more information on the Miiverse closure and the games it will affect, please visit the support site by clicking on the blue globe icon or the url below to launch the internet browser. From all of us at Nintendo, we sincerely thank you for supporting Miiverse all these years. We hope you’ll continue using Miiverse until the service ends."
Personally, I originally was rather upset by this change, as it means that the 3DS is literally losing its one remaining social point on the system, besides Streetpass and online games that almost no one plays. I do, however, have a few fond memories of this service, one of them being this post here. I think it's my favorite that I ever made.
Now it's not like it became super popular, but for the Miiverse community of the Nintendo Badge Arcade, 22 likes is nothing to sneeze at. However, I didn't always have the best time during Miiverse's existence. I remember this post being banned once because it evidently had "spoilers"...
Now of course I fought back and got it unblocked, but, still. Much proof has been found that the "administration" is composed of 'bots and nothing more, and well, I believe it.
It also doesn't help that Miiverse is composed of 1/2 true gamers that want to use Miiverse as a social aspect for fun and enjoyment, and 1/2 of kids who aren't old enough to use the 3D on their 3DS's and shouldn't have a social network in the first place. These kids are the primary reason I have strayed from Miiverse in recent years. They literally plague the network with hateful comments and obnoxious artwork that should be banned, but isn't. Why? Because you can't trust bots to do the job.
Overall, I still resent Nintendo for ending Miiverse at what seems so early, but at the same time can't blame them. This is of course my personal experience. What do you folks think? Will you truly miss Nintendo's first social network? Or are you fine with losing it permanently? Lemme know by sharing your own stories if you'd like.
