Of course comment score doesn't display value objectively or comprehensibly or indefinitely. Every topic has it's decay period, you may have made a good point, but if the community doesn't feel that way during lifetime of the topic, then that was a lost cause. If it really matters try again, as you just did. If it doesn't - leave it alone. There are many other things that HN doesn't do and leaves for people to figure out. Perfect? No. Good enough? I think so.
