I understand how HN calculates top posts (roughly, points divided by age to the power gravity) - but how is a user's karma calculated? I looked at the points in the threads/comments link on the top of HN, but the sum of the points there do not add up to my karma.<p>I'm guessing the answer to this is pretty simple and it bugs me no end that I don't know it :(<p>PS: Are all votes equal (when it comes to deciding the rank of a post), or does it depend on the karma of the voter?
I would like to know how the average is calculated. When I was a noob below 100 Karma, the average was regularly updated to reflect the actual average karma of all my comments. However, this stopped around the time I reached 100. Now, my avg remains fixed at 2.17, a value that I'm sure has nothing to do with my actual ($karma_total/$comments_count) ratio anymore. Does anyone know how this works?
It seems to be the sum of upvotes for anything you submitted, plus (or minus) any points from comments you've made; and a comment score of 1 is not counted.
Just something to note: I lost 40 karma points in a day when I was only downvoted 20 points... some of which I deserved, but still, something didn't work as expected.
