I wrote a very basic script to rank hacker news stories based on comment/score ratio, found it to be pretty interesting:

The idea is that stories with high ratio would mean active/intense debate, whereas low ratio means extremely insightful post. Both categories are very interesting to me.

Example output:

Sadly I never completed the project with a web UI.
