Erik Martin, the general manager of online community platform Reddit.com, spoke at the Nieman Foundation for Journalism at Harvard on October 9, 2013. During the discussion, moderated by Nieman Journalism Lab staff writer Justin Ellis, Martin explained how the site brings together niche communities by giving them wide freedom to post content. That freedom has also led to problems for the site, from inappropriate and illegal content to the misidentification of one of the suspects in the Boston Marathon bombings.
