I agree. Would have been much easier too. Unfortunately, HN doesn't have downvotes. The current model does incorporate upvotes, but we're seeing a lot more success training with like-kind labeled datasets + BERT fine tuning.

Thank you for trying the app and hopefully V2 will leave you feeling like the system is more precise.

"HN doesn't have downvotes"

It certainly does; although it's possible they aren't stored independently and simply "cancel out" an upvote, so maybe that's what you meant.

The interface and the graphs are really nice; even though basing the data on votes alone would be less interesting in one sense, I think the rest of the site would still provide value even with that simpler metric.
