Migrating living documents to a public source-control repository is fantastic. I can now subscribe to changes in policies (and maybe even propose my own).

When tumblr pushed their terms-of-use updates on users by displaying it in a modal lightbox over all the content, it had a link to the commit at the bottom.

There's now some confused kids with github accounts that didn't have one before, I hope they found their way back to tumblr again. :(

Is it open source? Like creative commons or something? Don't really see any notes about if someone could base their own sites documents on these. Well if you copy and paste any websites terms in to Google, you'll find lots of sites use the same wording anyways. Writing a terms of service and privacy policy seems scary and complicated without hiring a expensive lawyer.
