if github isn't at the top of this list whatever tooling you use to find sentiment is broken, fundamentally.

While HN has been negative on Github, October was its best month in terms of # of new orgs using it: https://bloomberry.com/data/github/

The rough math is based on % of negative vs. positive sentiment. There's likely a ton of noise around github that diluted the math. I can look into though, thanks for the feedback.
