Matt and I researched and co-wrote Mind Hacks using a wiki (MoinMoin). The wiki was just right for what we were doing – a brief, intense project with lots of information which needed efficient sharing and storing. Our use of the wiki was as part of the process, rather than aiming to produce a public, finished project (like say Wikipedia). We loved using the wiki as a provisional, shared, short-term memory – an ideal note taking device which allowed us to explore the ideas and information in Mind Hacks without getting bogged down by it all. We loved it so much that we’ve written an article about what wikis are and our view of how they are best used for the O’Reilly Network, What Is a Wiki (and How to Use One for Your Projects) – let us know what you think!
