What a great resource. A collection of patterns and anti-patterns (or actually resistance patterns) for moving forward with Wikis within your organization. Each entry begins with a short descriptor: "Most people want to see the upcoming meeting's agenda. Many would like to influence it or have material to add. So rather than sending email (attachments) to all your colleagues with the details of an upcoming meeting, you should send them a link to the agenda within your WIKI System."
Then proceeds to lay out usage, examples, common problems, etc (the site itself is a wiki so that you can contribute to it yourself.) The site also includes people patterns and forms (anti-patterns) that resistance can take, like "Manager Lockdown" "This pattern refers to the situation where a manager takes ownership of certain wiki content which is particularly visible and unintentionally discourages people from changing their content. The result can be that other wiki users who wish to contribute become hesitant about what content can and cannot be edited."
