>>pg+(OP)
I edit posts extensively before submitting, so I frequently see "Unknown or expired link."
This error is a minor tax on carefully worded, carefully considered posts. I've lost posts following this error due to back button/refresh mishaps. I could post, then edit, but then people are voting and replying to content that is changing.

Also a nice (although minor) feature would be to add a link back to news.yc when the expired link error occurs.
It's not that important but it would be nice not to have to delete the url parameters in order to get back (or find the bookmark again)
