As well as extra lined posts
The Miiverse is constantly evolving with smaller quality of life updates, and that's just fine by me. Posted on the Miiverse itself, Nintendo has given us info on a new update that adds a few extra features.
Most notably, you can now write posts and comments on multiple lines. Simple, but great in terms of making posts more readable. You can also list your three favorite game genres by going to your User Page, then Profile Settings.
It's a nice way to get people to know you better without giving out too much personal information. The Miiverse has some limitations for sure, but for Nintendo I think it's a great compromise, and a resounding success.
