The Git User's Survey 2009, announced by Chris Wanstrath, is currently open for participation and will remain available until September 15, 2009. All questions in the survey are optional, and participants can save their progress using session cookies, allowing them to take breaks if needed. The survey, which started on July 15, aims to gather insights from Git users, and the results will be published on the Git wiki once they are ready. Participants are encouraged to spend a few minutes contributing their experiences and feedback to help improve the platform.
