It's very easy to end up with messy/unusable history or even lose work when you have multiple people working on related parts of a project with outdated branches and limited git knowledge. I have been bitten by coworkers submitting preposterous pull requests because of a lack of understanding of what you can do with git and how it works that could have been avoided by taking the time to really grok git.
