The elevator pitch for tech-minded people is that wikis are to SVN as federated wikis are to git. Instead of a shared wiki that people modify, each user has their own wiki which consists of both pages they've made or forked, so information propagates back and forth between users. It's a really compelling idea and I hope they can make it work.
