GitHub Résumé
> As a software startup owner I really enjoy when people send us their résumés and they include their github account so we can see tangible work they have done.I sometimes feel very insecure when I read statements like this. I consider myself a good and a passionate programmer with "above-average programming skills", if there is such a thing. However, I have (so far) never been able to manage contributing to open source projects in any significant way. Sometimes I have been too busy with work projects, sometimes it has been a busy life at grad school, sometimes family, sometimes I have been plain shy, and so on. I have put together a bunch of great hacks at places I have worked, which sadly I cannot open source.  
But I see dozens of people whom I know who are naturally prolific in their oss contributions, manage to attract a high number of twitter followers, etc. and I wish I were more like them.Do startups really look at github contributions as the ultimate measure of one's tech chops or are looking for people who go that extra bit and make time in their schedules for contributing back to the community?
