At WordCamp Montreal 2014, I gave a talk on fears. In it, I told of a story from the Drupal community, that compares two approaches of open-source contribution: collaborative and isolated. I was unable to find it at the time to properly credit it, but my coworker Kathryn Presner just happened to mention it today: it’s by Angie Byron, and can be found on her webchick.net blog: Diaries of a Core Maintainer #6: A tale of two developers.
Enjoy!
