ASK HN: What is the logic that links would expire on HN?

Is it to avoid crawling? and indexing? If not, what else could it be?

As far as I know they store a continuation for each page you view. And after some time they just delete the continuation.

(Please look up call/cc if you want to learn more about this.)

The continuation model is conceptually nifty but the fact that all my tabs time out before I can finish writing my response to a post really drives me nuts. There's got to be a better way to persist these things. If I can hold a tab / response open for 8 hours then that will suffice for me.

Perhaps you can ask them to keep those continuations open longer for logged-in users. Or they already do this.
