Let me tell you about what I found there:
- People who don't know how to use Google to answer simple questions.
- People who don't know how to use Google asking about/wanting to trade Hoopa and Volcanion.
- Giveaways of/trades for hacked Pokemon.
- Ads for clans.
- Text-based RPs. Many of them centre around "Pokehumans." It's like 2007 all over again.
- Requests for girlfriends/boyfriends.
- Really amazing artwork.
Slightly weird, slightly hilarious. There is some very cool artwork, though. If you were considering checking out Miiverse (not sure why you would, but hey), then I suggest ignoring everything but the art.
