WordPress is certainly the most popular open source blogging platform, but how are development decisions made?
WordPress is actually a Meritocracy. It’s really quite simple and efficient, but the more you contribute to WordPress, the more weight your opinions carry when it comes time to make decisions. Probably the best example of this is Andrew Nacin. When Nacin began contributing to WordPress, he could only submit his bug fixes and enhancements for review. After showing his commitment to the WordPress community over three months and a hundred patches, Nacin was asked to be a core developer. Now, Nacin’s bug fixes and enhancements go right to the core.
I could write pages upon pages describing how everything works, but I’d certainly have a hard time explaining it better than Jane Wells did at WordCamp Portland 2010 during her session, How WordPress Decisions get Made.
