...if it had a like/dislike system like Youtube has?

Much better.

there would be no real difference.

There would be "Nos".

Every cheesy joke would get no bombed The no's would overtake the yeahs Youngins would take no's seriously Hatred would fill Miiverse, depression of little children would increase And then the Miiverse developers would remove the no button because of angry mothers, same thing that happened to Facebook a few years ago, with their dislike button

And then the world ends.
