Git is on the rise right now, especially in the Open Source Software development circles. Some even went as far as predict the death of Subversion. As much as I appreciate git (here is a link for you, if you don’t) and what it is doing for the Open Source Software, I have to agree with Brandon Savage:
Corporate America needs a centralized version control system. Subversion still offers this: Subversion centralizes the repository and simply checks out a working copy (versus Git, which gives you a complete repository). Corporate America still needs to have cannonical version numbers, and the ability to see the progress of a product over time as a single line – not a bunch of branches and independent repositories.
And this is true not only for the corporate America.
