The Miiverse idea is a really neat way of subtly promoting other games and making players feel like they're in a community, I think it may actually be the best idea out of everything they've come up with for Wii U.
That said, a lot of this is execution, and Nintendo often can talk for hours about how they're going to do tremendous things (ie: the new eShop), but they often don't follow through with concrete execution (ie: the eShop on the 3DS still sucks compared to iTunes or XBLA or PSN).
I don't really see Miiverse like Facebook though. It's more like a moderated Twitter.
