For me, leader board needs to be sorted by average karma per post, with a minimum karma required to be eligible to be on the list (like 10K points).

Agreed. I was surprised to find myself on that list; I've over 10K karma, but my average comment score is hardly impressive.

It's important to have interesting posts submitted but the comments are what really make HN.
