I'm not arguing to show points. It's fine without the points. Just saying that old pages are valuable to me.
As an example, when I got interested in GitHub last year (note: I mean as "what are they doing in this space and where are they going", not "what does it do"), I seriously went to searchyc and went through the Hacker News archives chronologically, skimming every single thread that has ever talked about it; it took days, but it was incredibly worth the time.
This has become such a resource for this sort of thing, that I've been trying to "get to know" the people I interact with here, building a tagging framework (browser extensions) that I can use to add little notes to users, allowing me to get a better feel for who they are, rather than some anonymous user: if nothing else, it helps me remember at all times that these are real people whom I am interacting with ;P.
So yeah, I guess I'm rambling now, but what I'm trying to say is: the archives are important. They may not be something you use every day, but when you do find a reason to use them it is one of the most valuable resources I currently know of, and I have to see it labeled as something that there is no point in improving due to "lack of use".
(my first post. Thanks to everyone who contributes, it's been an incredible learning experience since I learned about hacker news 8 months ago. And I say this as a non-hacker. This site has been immensely practical.)
Given the demographics, I'm sure the ratings will be used by someone for something. :)
Curiosity?
