Hmm, I'm not sure. Not because I want to "preserve my karma value" or anything but I am fearful of tricks like these because they seem to be somewhat close to "engagement" hacks. I do enjoy seeing new users and would like for there to be ways for them to contribute, but I am not really a fan of outright gamification. Personally, when I started contributing I was a bit hesitant because I didn't know how to "do it right"–it takes a bit getting used to commenting here, so I actually think a bit more detailed FAQ would be really nice. It's always fun to discover something new about Hacker News and share it around once you've been here for a while, and I think you could still keep some of those little secrets for people to find, but I think at least some of https://github.com/minimaxir/hacker-news-undocumented would be nice to know upon joining.

Speaking of the leaderboard, I was actually curious how it was organized: there are some people missing from it that I would expect to be there, like 'pg. How is that list generated?
