The concept of allowing anyone to change any document, at first, seems ridiculous and certain not to work. But it does. Most people want it to work, therefor it works. If it works for something as simple as web editing, why can't it work for source code?
We are convinced it does. Open Participation Software allows anyone to make changes to the codebase. Often these changes will be small corrections, other times larger contributions, and occassionally someone wants to destroy it. For the latter case (destruction), the answer lies in the effort ratio between the "process of destruction" vs the "process of restoration". If it is hard for the perpetrator to destroy, and easy for the community to restore, then the fun is gone and the perpetrator leaves.
