GeekUp is a grassroots organization that brings together tech-minded individuals in Sheffield, UK to share knowledge through social meetups. The meetups involve lightning talks by practitioners on topics like coding standards, development tools, and agile practices. They differ from other tech events by being participant-focused rather than commercial, and emphasize sharing and learning over networking over beers. The first GeekUp event in Sheffield was scheduled for May 7, 2008 at the Fat Cat pub.
