For the #67 contributor to Rails, Gannon McGibbon, the most common term in his commits is merge.
Of Gannon’s 135 commits, 51 are commits merging pull requests from other people. Gannon’s contributed fixes, documentation, refactors, and features, but the dominant theme in his contributions — both in his git commits and in his social activity on GitHub — is about merging PRs and enforcing coding standards. He’s a member of the committer team and he’s put in a ton of work there. He’s only been an active contributor since last year, so he’s averaging 9 Rails commits per month.
A big thanks to Gannon for this work!
