You’ll have to pardon me for linking to Ted Leung twice in short order, but the man is good peoples. This time I’d like to draw your attention to his presentation from OSCON on Open Source Community Antipatterns.
Ted’s talk is full of great observations from his time at OSAF and his ongoing work with the Apache project. Keep in mind that the presentation is on anti-patterns, so most of the slides describe what you don’t want to do.
