If you're really trying, you can accumulate over a hundred points in a day without posting any articles.
The site is basically a game if you're optimizing for points, and it's better designed than reddit because you have to actually know things to get them.
Have a niche programming language you like? Talk about it! Have a weird subset of computer science you wrote a thesis on? Write a few paragraphs a day on it! Have domain knowledge for something that isn't computing? "Debunk" all of the articles you see on it. Avoid controversial topics, because these don't grant you as many points. Go solely for uncontroversial deep dives into subjects you know about; it's far better for achieving as many points as you can possibly get as fast as possible.
You also have to have a particular style of writing. Detached, yet (at least on the surface) quite thoughtful. Use commas and semicolons rather than writing choppy sentences, and pay attention to your spelling; presentation is half the battle, and you'll have a hard time getting anywhere if you use less than stellar English. Otherwise identical comments will perform drastically different if there is a single misspelled "at least."
If you master these two steps, you, too, can farm Hacker News for points, get bored and eventually make another account when you want to feel the beautiful feeling of your words having attention focused on them once more, the sweet point-ticker on the top right of the screen offering you slow doses of dopamine throughout your workday that just doesn't hit the same if you're on an account with over ten thousand points.
I don't play this game anymore, as anyone can probably tell from this account and my willingness to break every rule I listed in this comment on it. It's fun to play, though, and I would recommend doing it if you have an aptitude for it; more people talking about more things deeply is always better.
