Exactly. HN emphasizes long-form posts much more than other forums which makes the commenters here very susceptible to this kind of analysis. Plus you can fit every single HN comment in RAM on a mid tier gaming laptop so it's even easier. I was trying to think of applications of this kind of data and the only thing I could think of was moderation tools/detecting ban evaders but what you've done seems much more profitable lol.
