How we hack Hacker News and consistently hit the front page

Yes, anecdata: A number of my own highest-quality finds have sink with barely a ripple on the "new" page.

Most legit posters have better uses for their remaining lifetime minutes of brain activity than to game HN in such a tedious exercise.

Various software mitigations to recover credit for otherwise lost quality posts occur to me, but the coding effort looks substantial.

I don't even understand how that's possible. Every time I tried to post a link that was already posted (by me or someone else), it redirected me to the original post (and upvoted it if I wasn't the author).

After observing that behavior 2 or 3 times, I assumed HN had some kind of deduplication system.
