An interesting talk [Google Tech Talks January 25, 2007]: “How Open Source Projects Survive Poisonous People- Every open source project runs into people who are selfish, uncooperative, and … disrespectful. These people can silently poison the atmosphere of a happy developer community. Come learn how to identify these people and peacefully de-fuse them before they derail your project. Told through a series of (often amusing) real-life anecdotes and experiences.”
By the way… Google Tech Talks are very interesting anyway.
