This is an interesting Google Tech Talk about how to survive poisonous people in F/LOSS communities. I probably find it interesting at least in part because there are a couple of very loud poisonous people constantly attacking the GNOME and Mono projects (both of which I'm involved with), but it's a great talk to listen to anyway.
I personally love the "Hostility" slide at around 29 minutes into the talk:
- Insults the status quo
- Angrily demands help
- Attempts to blackmail
- Attempts to deliberately rile
- Makes accusations of conspiracy (paranoia)
The bold/italic bit is a big hint-hint to the handful of people (not that they aren't also guilty of some of the others points) I'm referring to as the poisonous people around GNOME and Mono ;)
