I started using Git about six months ago for tracking notes (i usually use TextMate) and have been adding much more things into version control since then.<p>Even when not saving the data on a remote server, Git allows me to quickly start a repo when required and branch quickly and easily.<p>Version control provides amazing new possibilities to many kinds of data. Currently I am using Git not only for tracking Python, PHP and HTML/CSS/JavaScript projects, but also notes, papers, sometimes todo lists and pretty much anything text-based.<p>Tried writing and using a tool that unzips a Word doc and then adds the XML files inside to a Git repo, but the XML history is quite useless.<p>If Google Wave like Robots are possible in Docs, then would be great to add Git functionality to Google Docs. Or maybe Google will just improve the history views in its apps.
