Hacker News Reader

What happens to old posts? I would like a way to browse the archive.

Also, threads you comment on should show up in your profile so you can keep track of ongoing conversations.

Second the thread archive. I heard there was a secret YC video posted in an old thread but can't find it anywhere! :(

There's now a "best ever" page: http://news.ycombinator.com/best

I think an archive of all previous entries would be really helpful.
