Fostering an environment where user-developers are enabled and encouraged to automate and interface with our wikis with their code has allowed their productivity and impact to be greatly increased, has stimulated development work on the core code itself, and has allowed the establishment of a vibrant ecosystem of open source development around our projects.

In this presentation, I show what measures we took to stimulate that ecosystem and what lessons we learned about the impact it has on vitality of the developer community of our projects.
