Yes, I believe there is a need for a real, neat, fully functioning Pure Data Wiki. Such a wiki could serve as a valuable resource for Pure Data users of all levels of experience. It could provide a central location for collecting and sharing patches, examples, tutorials, and other resources. It could also be used to document best practices, troubleshooting tips, and other useful information.
I believe that there would be a lot of interest in contributing to a Pure Data wiki. There are many talented Pure Data users who would be willing to share their knowledge and expertise. A wiki would make it easy for them to do so.
I also believe that a Pure Data wiki would be a useful resource for the Pure Data community. It would make it easier for users to find the information, including the business information API they need, and it would help to promote the adoption of Pure Data.
