Wikipedia has "pending changes" which is a bit like a pull request type model: you make edit and it sits in a queue for a reviewer to approve. It's running on some pages on English Wikipedia. I'd love to see it rolled out to a lot more pages. On some language versions of Wikipedia, it's running on all pages: Polish, for instance.
