danlucraft/git.js. Wow, impressive. And potentially very interesting - git as a general synchronization mechanism is extremely practical and integrating git functionality into web applications could solve some problems well (e.g. when it comes to synchronization with other places, or of course for document-internal versioning). I have to take a closer look at some point, I already have one or two ideas on how I could use it. It's still quite rudimentary at the moment, but it's definitely worth keeping an eye on.
