Ask HN: An article gone missing?

I submitted an item here: http://news.ycombinator.com/item?id=1589055 It seems to have got two upvotes in the first hour, and all seems well. But I can't find it in the list of items http://news.ycombinator.com/news I wanted to see where it was in the ranking when it gained its second upvote, but I can't find it at all. Yes, I've clicked the "More" link - several times - but it's gone missing. I wondered if it had been killed, so I logged off and checked again, but the item itself isn't marked "Dead" so I guess it's still there. Just not listed. Very curious. Suggestions and comments to alleviate my confusion would be most welcome.
