FredDrake is the DocumentationTsar? for the Python programming language. He doesn't spend a lot of time writing in wikis, but has been doing more so for various purposes:

2. He's started a (currently private) wiki where he experimenting with world creation for a fantasy role-playing game he's running for a group of kids (including one of his own).
