Federated Wiki
[Ward] Cunningham’s vision is that you will have your own wiki, perhaps several wikis. When you see a page on someone else’s federated wiki that you want to edit, you can click “fork,” and the page is copied into your own wiki where you can edit it. The owner of the original wiki can then decide whether to merge your changes into the original page.
This is a really neat idea, but I’m skeptical about whether it can catch on.
