Still baffled as to what the point of the Miiverse actually is
It loads, you see loads of Mii's with random comments, you load your game
What's the point beyond a random, seemingly chaotic, home screen?
You are thinking about the WaraWara plaza.
Miiverse is a social network. The service is great. Microsoft/Sony would be nuts not to copy it. It gives singleplayer gaming a social aspect. You see something interesting in game, you can post the screenshot to comment. You get stuck on a level/part, you can post a screenshot and ask for help... I see Sony is allowing you to post videos/screenshots to facebook, I think that is by far the wrong approach, as you will be bugging the p%%# out of your friends who do not game.
Developers can leverage miiverse to increase traffic to their product on the e-shop... there is always someone asking "is this game worth it" and the responses are usually a ton of tiny little reviews for the software. Indie dev's and big publishers have made public comments on how it creates more sales that otherwise wouldn't happen.
Its a welcome addition, and they are still improving it. From what I hear they are going to be adding voice messaging, party chat, and open it up to smartphone/tablet/PC/Mac users...... think of it as Nintendo's implementation of facebook, but with a strong gaming discussion bent.
