I don’t know, when Discourse would introduce a community wiki feature, I don’t want it to reside on a different platform. I think the implementation should be the same like how the stackexchange network does it, simple and it works.
It shouldn’t try to be a complete system like wikipedia, just the basics. Allow multiple users to work on a thread or post, by marking it community wiki. That’s it.
This would make Discourse more suitable for placing tutorials/articles right on the platform itself, so I don’t have to deploy other software for this purpose.
I would totally love to have this feature, in my view it would make Discourse stand out even more compared to other forums. Other forums don’t support this as far as I know.
Use case example: Tutorials - Windows 7 Help Forums
Sometimes readers recognize small mistakes in a specific tutorial, and they’ll post it under the tutorial. The tutorial gets updated and the useless reply is left behind.
With the introduction of a community wiki the user can propose the mistake, and it’ll get updated without leaving behind useless replies. It also encourages other users to contribute.
I think the Discourse founders understand this concept better then anyone else, because of stackexchange. But I wanted to elaborate on this anyway for clarification.
