I don't know if this is the proper thing to do, but I have a suggestion for Ciel! Basically, it has a min-height for comments, which is fine, but when it comes to collapsed comments, I feel it's a bit excessive and gets in the way.

If we change this:

.comment {
    min-height: 138px;
}

To this so the min-height only targets the full comments:

.comment-wrapper.full .comment {
    min-height: 138px;
}

I feel like it would improve things greatly--there is enough padding in the collapsed comment areas to keep it from being too crowded, and not having 100 or so pixels of extra space around each collapsed comment really helps out in scanning them to see the flow of conversation.
