When looking at comments, I sometimes come across
| many, many sub-sub-comments
I don't really care about the responses to subCommentA,
so I a scroll past them, but it can sometimes be
a bit difficult to find the next subComment with the
same indent level (subCommentB).
In news browsers, this is taken care of by using a tree
view, so you can simply collapse the sub-tree which
represents a sub-thread that you aren't interested in.
For Slash, the next best thing would be to have a
within-page link from subCommentA to subCommentB,
