Twitter is a huge social media service with over 300 million active users, including one very active user with a high profile who lives at 1600 Pennsylvania Avenue in Washington. President Trump’s controversial Twitter use is a constant reminder that Twitter impacts politics, economics, and social movements around the world. In addition to being the president’s preferred mode for communicating with the public, Twitter has been the main platform of choice for movements like Black Lives Matter and MeToo. There are also important questions about Twitter’s role in our discourse, as its openness as a platform can lead to harassment and bullying. And the constant stream of information it provides can keep us glued to our phones, even at the dinner table. Today’s guest is a great person to talk to about all of these issues. Colin Crowell is the head of Public Policy, Government, & Corporate Philanthropy for Twitter. After graduating from Boston College in the late 1980s, Colin spent three years in Peru as part of a Jesuit-run mission project, and these Jesuit roots pointed him on a career path of working to make sure all people have open access to telecom and technology services. Today’s interview is in two parts. Right after recording the interview, Twitter announced that it would be banning political advertisements on its platform, so Colin called back in to share some thoughts on this latest development. Be sure to stay tuned all the way to the end. Don’t forget to subscribe to AMDG wherever you listen to podcasts, and leave us a nice review on iTunes.
