Neat - I completely forgot about this. If anyone's interested in these different views on top of HN I created http://yahnr.com/ a while ago that just shows the top stories by vote from the past 24 hours, updated every 15 minutes.

I mostly did it as a way to generate a "pseudo-static" site that is entirely hosted on S3 with a job that just dumps JSON files to it every 15 mins.
