Another good point from Lucas Billett: “Define the wiki community as the people who are allowed to see the content.” Turns the usual corporate objection to MediaWiki on its head. The communities are usually much larger than and of fewer number than at first though.
The latest Between the Brackets with Lucas Billett talks about using a wiki in a decades-old organisation — a factory that’s been in business for 160 years. I can’t imagine what it’s like to work in an place like that! It sounds like their use of MediaWiki is pretty interesting too.
