#2Yes, I've noticed this too -- it seems like it happens when I "take too long" looking at a New page. Since it doesn't seem to happen to me much on the home page, so maybe tied to the number of items posted since landing on a page?

#3I was just commenting to a co-worker this morning that I have been receiving a lot of expired link errors lately and that HN's session expiration time must be short.
What language is HN written in?
I leave HN open in two tabs all day: one for the newest articles and one for the top articles. Article links to other sites don't expire because they're direct links to an external page. However, most internal links do expire if I haven't refreshed the page in an hour or so.

HN is written in Arc - a Lisp dialect coded by PG. You can see it here: http://arclanguage.org/

#5Same here. Making my noon reading of HN pretty annoying. (Read front page, hit more, get expired, go back, reload, hit more ...)

#6From what I recall, this is because the 'More' link is implemented using closures, which get garbage collected after a while. So if you take too long and a GC has happened in the meanwhile, the link will be broken.

It's been an known issue for years.

#9I've been noticing it more frequently as well. It has changed the way I use HN. Now, I quickly scan the first page and open interesting stories in tabs. Then I quickly click More and do the same. Wash, rinse, repeat two or three times depending on how busy I am.
Another related issue: the expired page is remarkably stark and unfinished in comparison with the rest of the site. A minor nit, but since it shows up so often, it doesn't look great to the uninitiated.

#10Happens to me all of the time - it's pretty annoying. It would be great if HN used pretty URLs (e.g. http://news.ycombinator.com/news/2), or at least URLs that didn't expire.
