I submitted this story to Hacker News about an hour ago. It collected 13 points before it dropped off the bottom of the New page never to be heard from again. But at the same time there was another story on the front page that was an hour older and had fewer points (9 at the time, 12 just now). So my submission should have appeared on the front page. But it didn't. I wonder why.
In case you're wondering, no, I don't really care that much about this particular story. But I'm in the process of trying to promote my movie, which has forced me to pay attention to such things (more on Reddit than HN, but they supposedly use the same algorithm).
