joining me is hayes davis, sarah frier and nathan brown., is project lightning as dramatic as it sounds? how exactly would this work? sarah: what this would do is help people understand why to use twitter. there is a lot of confusion among people who are not journalists and politicians and celebrities. thinking this is a product that is not for me. this could help bring people in -- people who want to be first to know what is happening with the charleston shootings or maybe first to know what is happening in sporting events. it would be organized in one place. it would really help twitter with its value proposition and its advertising. it would allow them to sell different kinds of ads and monetize it differently. emily: i wonder how big a business shift this is. one headline said twitter is killing twitter to save twitter. hayes: i think that is a little extreme. twitter has been a transformative media company since the beginning. i think they are really starting to own that identity with project lightning. for me, twitter is hugely import
