The solution is to avoid capturing the state of the user on the server, passing it in the URL instead. That way nothing need expire about the link.

The solution is for someone else to create a better site that's actually maintained and start migrating people away from HN. A more neutral foundation would be better anyway, imo.

User state is current captured in a closure in the single process single threaded HN server (running a custom lisp). The solution is to not do that.

Maybe it should redirect to the New page.
