Well you don't get to see other people's comment scores anyway. What I meant is for your own comments, seeing a score of +1 doesn't carry the same information than +15/-14.
Yep, I know. I was just riffing on your idea; I think the ranking algorithm should be tweaked a bit. Popularity contests don't lend to great debate or conversation. They tend to shut down one side at the expense of the other.
