Foursquare has lost product manager Christen Duong. After two years with the company she announced plans to move from New York City to San Francisco. Christen is making the move so she can join another starup, Flipboard.
Christen was a fast moving achiever for Foursquare, over her short time with the company she helped roll out a completely redesigned mobile app. She also helped role out the Explore tab for discovering new venues and helped in the development of contextual pages that show tips from friends alongside pictures they post.
