I dug into the collapsing code recently because I wanted to make a script that collapses HN threads by default. In other words, only the top-level comments would be shown at first. To me this makes more sense. If I am interested in continuing a thread, I can expand it. If I am not interested in continuing, I don't want to have to scroll past its children. According to the comments here, maybe I would be better off implementing my own collapsing scheme.
