It seems people are more prone to input their opinion when it's negative. Although negativity is not a problem here and now, I think it would be better to try keeping it that way.
Imagine you're new here, you decide to post thought provoking, crazy content and a few people dislike your posts. It's no big deal, right? But this new member doesn't know the forum very well and will probably don't appreciate it that much. It's kind of similar to what happened to our latest member, Eva, who didn't like having her user title set to "Lurker". It's no big deal, but if you're new here, it can possibly turn you off from posting and enjoying the forum.
