I do not build my resume from scratch. Often it is exported to PDF from some other service. I store this PDF in the git repository for my website, which is published on GitHub Pages. So inevitably, my resume has snapshots.

File formats like PDF do not lend themselves to version control. It would be hard to merge improvements on a shared "feature" of your resume from one branch into another branch.

I tend to use the .doc format and edit locally on my computer, and only export to PDF when I'm ready to send out the resume. I'm not certain if .doc would be much easier format to share changes on a resume.
