Ask HN: What are current karma thresholds?

Can anyone shed some light on this? I have an irrational need to associate numbers with a goal :)

At 1,000 karma, pg mails you an autographed copy of On Lisp.

I just broke 200 and got the ability to downvote comments...can't downvote submissions though, not sure if that's even a possibility actually

Nobody can downvote submissions
