I [tweeted this already][1] but I thought it could use some expansion:
Enable decentralized git workflow:
git config alias.serve "daemon --verbose --export-all --base-path=.git --reuseaddr --strict-paths .git/"
Say you use a git workflow that involves working with a core "official" repository that you pull and push your changes from and into. I'm sure many companies do this, as do many users of git hosting services like Github.
