HackerSalt 🧂

https://www.hackersalt.com

HackerSalt is an app that lets you see how "salty" any HackerNews commenter is. Search by username or browse the ranks of the "Saltiest". We've taken the open source HackerNews dataset and used sentiment analysis to generate summaries of usage across commenters' lifetimes.

Please explore. 🙂 We've prepared visualizations & dashboards of commenters' activity for your curiosity. Just be prepared there's some really nasty trolls out there.
