My resume is my resume. My personal code is closed-source, with the exception of a couple of bits for presentations and an archived project for which I am a maintainer. You could say that "well, that one archived project is your resume," but that would be foolish (not that you are saying that, but it does follow from all of this) because it has little to do with what I actually do.
More than anything, though, I kind of find all this "anoint the buzzwordy startup as the new X" stuff silly. Maybe one company in ten would actually follow a link to Github or Bitbucket on my resume, regardless of the content. At least for now, the resume is the new resume.
My current personal project is a cross-platform game framework for Windows, OS X, Linux, Android, iOS, 360, and WP7. It may be commercializable, and as such open-sourcing it makes little sense. If it's not, then when I'm done with it I'll likely open-source it.
