The highest threshold for unlocking features HN is at 501 karma (comment downvoting), which is not a lot and is mostly there to limit abuse.

More importantly, it doesn't affect the submission ranking algorithm at all.

I hear that if you reach rank 50 or above on the HN leaderboard you gain the ability to have your posts appear with <blink> in rainbow colours but those who have it are too wise to use this power.

More seriously these posts got me interested in what features besides downvoting would be added at various karma levels which led me to your git page on the topic. Linked here for others interested:

I appreciated your joke because the latest trend I hate about reddit are the party-parrot-esque avatars. I immediately scroll them off the screen, couldn't care less what they have to say. (I say this as a lover of the party parrot, but, time & place people...)
