James Robertson of Column Two points to a fun report from Patrick Lambe that describes the "archetypes" present in the Act-KM online community (mailing list), Mapping the Culture of an Online Community (pdf). The drawings of each type are almost as good as the breakdown into these types:
- The Mediator
- The Energy Vampire
- The Lurker
- The Angry Little Man
- The Beginner
- The Hostage
- The Backstabber
- The Professor
- The Sophist
- The Visionary
- The Guru
