The moderation team does a good enough job already; they will and should continue to stick to their guns about "good faith" discussions and that will be enough of a frustration to people repeatedly posting thoughtless or incurious comments that most discussions will continue to be reasonable and sensible. There are still pockets of that here. I think the other commenter nailed it about this being a result of increased popularity but I also think that will cool down as the less curious learn to prefer different communities.
