Ask HN: Unknown or expired link.

I cannot tell you how many times on this forum I've been browsing the threads only to suddenly get this error page/message:

"Unknown or expired link."

It would seem to "make sense" (from my way of thinking, especially on a tech-savvy forum like this) to automatically redirect the visitor to the new posts rather than showing them this error ... or at least put a link on the error page that gives visitors the proper URL to click after the error message:

Unknown or expired link. <a href=http://news.ycombinator.com>Click here for the newest threads/posts</a>.
