Dear Linuxers,
When you get the time, please watch Linus' talk on Git at Google[1]. It helps if you have an idea of what Git is and why it's different from the other source (version) control systems around, though not necessary. This is a very informative discussion. It's about 70 minutes in duration.
HTH.
