I think the leaderboard is a very good reward for the people who spend quite a lot of time on submitting quality links and contributing to discussions with good comments. every upvote on Hacker News (especially in the comments section) is hard-earned IMHO. the community upvotes quality, and that's one of the main reasons why I love to read links from Hacker News and take part on discussions here. for me it's really rewarding when I see that one of my comments / submissions got an upvote (note: I'm no karma-wh__e by any means!)
