Slightly off topic but the Git model is generally interesting. I'd like to see it used for writing, publishing and sharing ideas (like it can code). To me it seems like it could be a great system.
Check out flashbake. It's a set of Python scripts for automating git and adding various metadata to commit messages, and was written as a personal writing tool for Cory Doctorow.
