Also, the other day, I replied to someone, got downvoted to negative something, and then, as an experiment, I copied the comment, deleted it, and pasted it into a reply to the parent of the comment I originally replied to, and got upvoted +8.
It's science.
This goes double for being an early riser on the East Coast!
Until recently I commented early in the morning for a few months. I fared well - I usually got the top comment in the thread, unless a power user struck first. I don't think my comments were particularly insightful, but the timing worked - they would stay above the fold long enough to pick up an upvote.
The "shape" of a comment also seems to affect the rating. A quick summary followed by several reasonable-sized paragraphs is a local maximum for gathering karma.
I rather have no public karma score or leader board. It adds zero value other than comparing e-penis.
Karma doesn't necessarily reflect the quality of comments. More often than not it reflects how much time you spend and how popular you are here (people will often blindly upvote users who adds nothing interesting to the discussion but is a popular user at HN) and how fast you can submit TC article.
All communities have some means to keep track of pecking order. I really have no idea if karma is better or worse than other methodologies. <shrug>
It's definitely better than simply listing the user's post count next to their name, which a lot of fora still do.
Now if you'll excuse me, there's a particular lever that I need to go and push...
I have just shy of 13k karma and I'll admit that my rise from around 3k->10k was driven entirely by, first, trying to get on the /leaders page, and then into the 10K club ;-) A pointless, egotistic goal but good things came out of it. Firstly, most of my comments and posts weren't frivolous so people appreciated them at some level. Second, spending so effort here made me feel more a part of "the community" and has led to some interesting extracurricular discussions and opportunities.
Not everyone needs numbers, scores, or money as motivators, but some of us find it a handy metric. Being a points scorer doesn't mean the outcome for third parties is necessarily negative and I certainly wouldn't do "anything" just to score a few points, that's for sure - just like not all rich people are evil money grabbers.
I will note that many of the benefits you cite could have occurred even if karma were not the means by which pecking order is tracked here. So I don't think it really says much about karma per se.
But thanks for sharing.
My take is that if you identify with HN and many of the "hacker" standpoints and pursuits, you're not an outsider here. At least, I would hope one wouldn't feel that way. More than most other communities I've experienced online, HN isn't very cliquey nor very focused on one's vital stats - there are people from all corners, all genders, and all races here but it's already anonymous enough that it's hard to tell. Being a geek and taking an interest in new things are probably the only prerequisites to be "in" here. I think that's a great thing.

Sure, but from different people. Without my side goals, I probably wouldn't have spent as much time on my comments or "contributing" here generally. Of course, I wouldn't dare to suggest HN would be any better off with more people like me ;-)
I'm a little disappointed to see that some of the top replies in this discussion right now are people who've obviously put some thought (and presumably effort) into working out how to post in ways that maximise HM karma.
It feels a bit to me like the old problem of not having the right metrics to measure and encourage the goals. If people are deciding when to post based on how it'll affect their karma, presumably that means sometimes they're choosing _not_ to contribute to the discussion "cause the karma payoff is too small". That's a bit sad.
(Which I guess is an easier to hold view from a lowly ~300 karma account...)
HN is a bit different though as it's more of a meritocracy and the 'top posters' aren't just people who never log off.
@edw519 get more karma in a day than me in some 388 days.
