I do like that idea. I think I tried it a while ago, but users complained that without comment scores it was too hard to figure out what were the most interesting comments in a thread. Is there some other way to show what the most interesting comments in a thread are? How about if I displayed the point totals for subtrees, but not for individual leaves? Would it solve the problem if you could follow other users, and…
You could show a simplified indicator of Great Comment, Good Comment or Bad Comment (or a similar set of values) so that users can skim a thread effectively. It's hardly a model community, but I think Engadget used to have a system like this.
Perhaps there should be a "best comment in thread" indicator or something as well?
