I think I tried this when I was writing it, and without numbers the page seems too unstructured. You need something, and bullets don't do it.
One a 'bombastic' site such a small change would hardly be noticeable. HN is like a laboratory experiment.
This site does something similar: http://slickdeals.net/
edit: I just realized that by doing it this way, I negate the point system. Oops.
