An interesting rating of Ruby open source contributors: https://opensource-heroes.com/contributors?country=&language=ruby&button=filter
Looks like 5 most popular organizations doing Ruby open-source projects:
- rails
- homebrew
- thoughtbot
- github
- jekyll
And top 5 individuals
- ankane
- bayandin
- kilimchoi
- ryanb

For some looks like the primary language of their repositories is incorrect. But anyway it’s an interesting rating.
