Git(hub) is for collaboratively writing major or minor software projects under which books written in latex should fall. Is there any interest in writing a book about a rationality topic in that way? I want to learn the ins and outs of some kind of versioning system and write something major in latex.
Under git's model, there will be as many 'versions' of the book as there will be authors. Remember that most major projects on github have many branches. Git doesn't treat any branch as 'priviliged'.
This would definitely be a very different way of collaboratively producing books than, say, the wiki model, where you have a central branch that everyone simultaneously collaborates on. Under the git model, everyone would essentially be writing their own book, and if you liked some of their articles you could insert those chapters into your 'own' book as well.
If you start this project, put up its github address here so that the interested (including maybe myself) can fork it.

relevant - https://www.writelatex.com/ I don't know what kind of version control it has, though.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
