I think Nintendo should integrate the miiverse app into the OS of the Nintendo NX. Miiverse now takes about one minute to boot up on Wii U and a bit longer on 3DS. This is really unacceptable because Miiverse is the only way to message your friends and see the activity feed. Also, miiverse has real notifications, unlike the shitty ones the console has. Like the PS4 they should have the activity feed there when you boot up your system and have the communities, messages, and notifications on top.

Thoughts?

I would certainly use miiverse a lot more if it was effectively instant.

I have no reason to believe miiverse is going anywhere. Nintendo has invested to much time and effort into making it work, and people who actually use it, love it. It just needs to work faster (instant).
on a side note, I'm not a fan of the updated look, i like they way it was at launch.

Nintendo should improve Miiverse right now.

I agree, but it'd have to be vastly overhauled for both 3DS and NX.

Since Nintendo is being more active in the smartphone market. Why not make an app for it?

Yea I'd like to see that, I don't particularly use Miiverse often for some of the reasons you describe, Loading times etc but when I do I always have some fun on it and leave with a smile :) having it appear in the main OS screen or an activity feed like you said would definitely make me check it a lot more.

As long as it doesn't clutter the screen then I wouldn't have a problem with that, but hopefully they'll make Miiverse itself better first and foremost.

Allow miiverse on android and ios so that I can make shitty drawings on my phone!

I agree, miiverse should be implemented in the NX but I wouldn't change it, it's fantastic.
