Over the April 26-28 weekend, some 120 developers, entrepreneurs and mentors from the public and private sectors participated in the first-ever Startup Weekend Government. They worked for 54 hours nearly non-stop at City Hall to create apps that use open data from Seattle, King County and Washington State. Sol Villareal wrote a great account of it on the Mayor’s Blog: http://bit.ly/IVTNvI. Check out the winning apps.
