it's worth noting that the "second-chance pool" doesn't have any kind of hard timeout on it–two days ago I got an email invitation to repost a link from <i>five months ago</i> (reposted: <a href="https://news.ycombinator.com/item?id=30438015" rel="nofollow">https://news.ycombinator.com/item?id=30438015</a>), and when I asked why, dang explained it was because he was looking to send a second-chance resubmission invite for another, unrelated submission, chose another duplicate of something I submitted, and then went on a rabbit-hole that ended up with him coming across a different submission (the one linked above) from my account. I think that's pretty cool, and I had no idea it worked like that.
