Most active GitHub users (

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at from Sat, 17 Nov 2012 22:21:52 GMT till Sun, 17 Nov 2013 22:21:52 GMT.

Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:

  .filter((user) -> user.followers > 200)
Something went wrong with that request. Please try again.
