Patheos: New Social Media Site Aims To Promote Thoughtful And Nuanced Conversations. “Letter is a new website that rewards thoughtful discussion and hosts a variety of conversations. People write ‘letters’ back and forth to each other in a long style format. So anyone can read a variety of nuanced conversations happening on a variety of topics, but you don’t have to worry about trolls getting in and ruining the discussion.” Took a brief look at the site. What I saw I really liked, but there wasn’t a lot of content available yet.
