Open Source Software and Skin In the Game
I have been tinkering in the Haskell programming language recently. Trying to up my game, I have begun reviewing and working on issues in the Cabal project. Soon after submitting a (very) small pull request, the project admitted me to being a full contributor. I was surprised. I'm a Haskell newbie, and it's not my project.
A developer linked me to this post which argues for promoting random contributors to full collaborator status. Its author argues that if someone owns the project as his own, he's a better developer for that project. Admittedly the promoted contributors are not completely random. The author looks for signs showing the developer is responsible and can be held accountable for his work. And (in the author's experience) this has led to higher quality programs than his overseeing all commits.
