Why doesn the Cookbook use a Scheme-based wiki?
None of the available Scheme wikis provided all of the features which we considered important for the Cookbook, and we felt that it was more important to provide a usable Cookbook, than to “eat our own dog food” and delay the Cookbook while suitable wiki features were developed in Scheme. Features that were considered important, which were not available in existing Scheme wikis, were: user authentication (for tracking changes and discouraging wikispam); revision control (for data integrity and to simplify the job of the editors); and a large number of more minor features and configuration capabilities that have been battle-tested and refined over time in mainstream wikis.
