It went from like every story getting hundreds of comments to most posts getting no more than a couple dozen comments per post.

I feel like it was a mistake to label the gray comments "pending." They are just as readable as aany other comments, but the idea that the comment isn't "official" yet seems to put people off from commenting. I look through them and approve good ones but honestly there isn't that much to recommend. I have yet to see any of my Clashtalk friends over there for instance.
