I've been using git for source code management for over a year now and I'm totally hooked. I won't rave about all the usual reasons WhyGitIsBetterThanX since it's been done already. Instead, I'm going to share how I use git for easy agile development. The basic idea is to never do anything in the master branch except use it to move changes between the remote repo and local branches. Keeping master clean takes very little effort and will save your bacon when you get into trouble. The example I'll use here is working on a story to render title text in a bold style on a page.
