My 3DS being now my only official gateway into the Miiverse... I gotta say it ain't great. I suppose the Miiverse you access on the 3DS is just some form of the 3DS web browser that is on it, because it is slooooow. But I was now able to sign up for Nintendo ID, so I guess I could just check the actual web browser version since that's actually quick to load.
Also if those smartphone apps they announced for it to ever come out I'm sure they'd be a much better experience than the 3DS.
