You can when you get a high enough karma.

Really? What's the number?

[jmatt]

I'm not sure. But I have enough karma at 85. I think the number has changed over time, but I'm not sure.

Maybe PG will share it with us or someone has recently hit the magic number?

I have 867 karma and can't downvote stories. At some point there were talks of letting the top X downvote stories but I don't think it's been done.

[jmatt]

Yeah it's calculated. I thought you were talking about comments. Or it was last time news.arc was released by PG

  (= 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)))

You sure you don't mean comments?

[jmatt]

Yeah my bad, I'm talking about comments.
