Open Twin Cities co-founder and MNCOGI board member Bill Bushey braved the stage at Bryant Lake Bowl on Monday to sing the praises of open data, along with the Minnesota Secretary of State and Minneapolis’s chief information officer. It was all part of the Theater of Public Policy, an improv group that combines comedy with free-wheeling discussions of serious stuff. The house was packed to hear about the availability of large data sets, privacy breaches and other typically dry matter made more fluid by the wide beer selection and live music. Also spotted in the audience: MNCOGI board member Helen Burke.
