HN's second-chance pool is a way to give links a second chance at the front page. Moderators and a small number of reviewers go through old submissions looking for articles that are in the spirit of the site—gratifying intellectual curiosity—and which seem like they might interest the community. These get put into a hopper from which software randomly picks one every so often and lobs it randomly onto the lower part of the front page. If it interests the community, it gets upvoted and discussed; if not, it falls off.
If you see a submission that didn't get attention and which you think is particularly good for HN, please tell us at hn@ycombinator.com! We love getting those requests and usually add them to the pool. It's fine if it's your own article, but we like it better when it's just something you ran across and recognized as good. That's more the kind of interest that HN is for.
A related list is https://news.ycombinator.com/invited. Those are old submissions that we ran across and thought deserved attention, so we emailed and asked the submitter to repost it. Yesterday's top story was one of these (https://news.ycombinator.com/item?id=26982286). They all go into the second-chance pool, but maybe it's interesting to see them broken out as a subset too. (If you don't have an email address in your profile, please put one in so we can send you repost invites!)
If you read the old explanations I linked to, you'll see that the original plan was to turn this system into software that anyone can participate in, likely as a new way to earn karma: users who discover second-chance links that hit the jackpot (that is, which interest the community) would get karma along with the original submitter. That is still the plan! We're just slow.
I think that's about everything there is to say about the second-chance pool. Questions, feedback, ideas, and views are welcome as ever. And please, everybody keep an eye out for obscure, out-of-the-way stories that got overlooked and let us know when you run across them. It's one of the best things you can do to help make this place more interesting. Best of all are the kind that can't be predicted from any existing sequence: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor....
Poster of yesterday's top item here - thanks for the email! It was completely unexpected (to the point where I needed to convince myself it wasn't a weird spear-phishing attempt) and I appreciated the opportunity to share the story again with the community. In my opinion it's a fantastic example of user-centered design, with a great story.
[Disclaimer: A write-up of mine is one of the current front page items thanks to second chance, as well.] It's a great feature, because, as long as you want just to share and do not care too much about your karma (you'll lose half of it), you don't have to manage submission dates, like figuring out, if the right audiences will be present right at that moment to pick it from the stream of new posts.
Shout-out to dang & Scott, who are doing fantastic work!
I think what they mean is that if your post gets to the front-page via the second-chance pool and then gets 100 upvotes, your karma increases only by 50.
We started doing this in late 2014. There's an explanation at https://news.ycombinator.com/item?id=11662380, with links back to others. We've talked about it in comments and whatnot (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que..., https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...), and have intended to publish the list, but only did so recently. We're slow.
