The nonprofit organization Sunlight Foundation has been keeping track of the tweets politicians didn’t want you to see anymore. The site, called Politwoops, saved the tweets deleted by lawmakers. For the past three years, it tracked thousands of blunders and position changes. It also helped track how Twitter was being used for political discourse. But last week, Twitter suspended Sunlight’s access to its information, shutting down Politwoops. The move raises questions about how the social network balances privacy with the public’s right to know what their politicians are up to online. WBEZ web producer Chris Hagan tells us more.
