Show HN: Tracking HN rankings over time (hnrankings.info)

I built this site as a weekend project to teach myself Django. It turned out to be a pretty interesting way to visually view how stories rise and fall on HN over the course of the day.

I am planning to do some more analysis of the data soon and add more features to the site. Any suggestions of useful metrics would be helpful.

very cool! i like the way to navigate and browse stories.

thanks for making and showing!
