One thing that seems to be a somewhat decent feature with the WiiU is Miiverse. It is social network for the WiiU community, that will be expanding to smartphones and web-browsers soon. The release date is supposed to be sometime in April or May. It should be interesting to see if it will be a hit or just another attempt by Nintendo to do something out of the ordinary.

"Miiverse will be key part of the Wii U console and will be available at launch. The social network will connect players who have Mii profiles on the same system, and connect players from around the world via the Nintendo Network. Miiverse will be free to use for all Wii U players and won’t carry a price nor a subscription plan. Miiverse is based on web-browser technologies, which means it will be accessible from any browser enabled device in the world, including phones, tablets, and more. To be a tad more specific, Miiverse producer Kiyoshi Mizuki stated that the app would be available in April or May, though a firm date has yet to be pinned down."
