The problem I see with this is that upvote distribution across comments isn't linear. Just because you are at the 1/2 way mark doesn't, in any way, mean that the comment can be considered middle ground. A thread with 100 top-level comments might only have 2 or 3 which the community considered insightful. In which case, the 4th comment isn't really any better then the last (it might be a difference of 1 or 2 votes). Maybe a way to indicate that a certain branch represents X% of all votes? Dunno, stupid idea probably.
