"Wikis are at their best when a small number of people are working intensely on related material. They're messy, immediate, and a powerful way of sharing thinking space with your collaborators.
Once you've used a wiki for a project, you'll find it hard to go back to regular methods. You'll find yourself using wiki syntax in emails, and your own WikiWords in conversation. Using the wiki as your notebook will ensure you don't lose the seeds of good ideas, and spending time browsing and gardening will keep those ideas returning when you need them.
