I found this out via a tweet from Mike Henke and then also saw it mentioned on the GitHub blog. Every year Git runs a survey of Git users to get feedback and help drive the future development of Git.
You can answer as many or as few questions as you like, and you can even return to the survey later and update your answers. The survey will be active until October 15th, and the results of the survey will be made public via the Git wiki after that. The survey can be found at http://tinyurl.com/GitSurvey2010, why not complete it today?
