Ask YC: How do the Karma points work?
How are some comment points negative?
What is the difference between new and newest?
- senthil_rajasek 18y agoDoes anyone know what algorithm the karma point system follows?
- aston 18y agoIf you're asking about front page ranking. it's been released with arc2, and looks like this: (= gravity* 1.4 timebase* 120 front-threshold* 1) (def frontpage-rank (s (o gravity gravity*)) (/ (- (realscore s) 1) (expt (/ (+ (item-age s) timebase*) 60) gravity))) (def realscore (i) (- i!score i!sockvotes)) (def item-age (i) (hours-since i!time)) Which is summarized, also in the code, as "[net] Votes divided by the age in hours to the gravityth power."
- brlewis 18y agoWhen you get more karma you can vote comments down. That's how they go negative. New (in the title bar) and newest (in the URL) are the same.
